Personality
1) Personality is affected by about 40% heritability. Temperament and extraversion is also affected by genetics.
Schizophrenia
1) Schizophrenia is a mental disorder marked by loss of contact with reality; symptoms include hallucinations and delusions.
2) People born in urban areas more at risk for schizophrenia
3) Possible causes include the lack of a chemical called reelin and also by a defective gene for reelin.
4)Between 63 and 35 percent
Autism
1) Autism is a pervasive developmental disorder of the brain characterized by lack of normal social interaction, impaired communication and imagination, and repetitive and obsessive behaviors.
2) 16 in every 10,000 people
3) males
4) Autistic babies may fail to recognize emotional signals of others, may refuse to cuddle or make eye contact, may speak in a sing-song voice, have repetitive behaviors, and are obsessed with certain subjects, rituals, or routines.
5) Several may be involved in cases of varying symptoms and severity. HOXA1 is a gene that is a likely candidate for playing a role in autism.
Abby Cochran and Katie Steeves
1) there's 5 groupings of traits: extraversion,neuroticisn,conscientousness, agreeableness, openness. they suggest a heritability of about 40%.
2) schizophrenia is a mental disorder marked by loss of contact with reality.
3) the risk of schizophrenia is 10 times as great among siblings and offspring of schizophrenics. adoption studies suggest that increased risk comes from genes not environment.
4) a prenatal viral infection, infections during pregnancy, and lack of the chemical called reelin in adult brains.
5) it is between 63% and85%.
6) autism is a pervasive developmental disorder in the brain, characterized by lack of normal social interaction, impaired communication, and imagination; and repetitive obsessive behaviors.
7) 16 of every 10,000 people
8) it affects males the most
9) a baby may fail to notice emotional signals of others, may refuse to cuddle or make eye contact, show repetitive behaviors, and are obsessed with certain subjects, rituals, or routines. 3 out of 4 are mentally retarded.
10) it has a strong genetic basis. different genes may be involved in cases of varying symptoms and severity. variance of the gene HOXA1, a gene involved in the development of the brain stem, fits with findings of brain abnormalities in people with autism. it results from genetic predisposition combined with environmental assault.
Personality. 1. certain aspects of personality appear to be inheredity. A large body of research strongly suggests that shyness and boldness are largely inborn and tend to stay with the person throughout life. The main environmental on intelligence seem to occur early in life.
Schizophrenia. 1. A disorder characterized by loss of contact with reality and by loss of contact with reality.
2.Lacking a Chemical called reelin. 10 times as great among siblings and offspring of schizophrenics as among the general population. & twin and adoption studies suggest that this increased risk comes from shared genes not shared environments.
3.Lacking a chemical called reelin.
4.contribution of genetics (63-85%)
Autism> 1. Disorder of brain functioning characterized by lack of normal social interaction, impaired communication and imagination, repetitive obsessive behaviors.
2.16/10000 people
3.Male
4. An autistic baby may fail to notice the emotional signals of others and may refuse to cuddle and make eye contact. Severely autistic children often show behaviors such as spitting rocking, hand flapping, and head banging and are also obsessed with certain subjects, rituals, or routines.
5. No single cause but runs in families and seems to have a strong genetic basis.
Intelligence 1. They've proven that adoptive childrens IQs are consistanly closer to the IQs of their biological mothers than to those of their adoptive parents and siblings. 2.Identical twins are more alike in intelligence than fraternal twins. 3. The measured genetic influence increases with age. The family environment seems to have more influence on younger children whereas adolescents are more apt to find their own niche
Personality:
Analyses of five major groupings of traits extraversion,neuroticism,conscientiousness, agreeableness, and openness to experience-suggest a heritability of about 40 percent.
Schizophrenia:
Schizophrenia is a mental disorder marked by loss of contact with reality;symptoms include hallucinations and delusions. Schizophrenia is ten times as great among siblings and offspring of schizophrenics as among the general population; and twin and adoption studies suggest that this increased risk comes from shared genes not shared environments. Some possible causes are prenatal viral infection carried in the blood shared by monochorionic twins.People born in urban areas are more likely to be schizophrenic then people born in rural areas. The estimated genetic contribution is 63 and 85 percent.
Autism:
Autism is a pervasive development disorder of the brain, characterized by lack of normal social interaction, impaired communication and imagination , and repetitive, obsessive behaviors. The rate of occurrence is an estimated 16 out of every 10,000 people. Autism affects mostly boys. The symptoms are that they fail to notice the emotional signals of others or may refuse to cuddle and make eye contact, may speak in a sing-song voice, and may pay little or no attention to the listener. A severely autistic child may show repetitive behaviors such as spinning, rocking, hand flapping, and hand banging, and are obsessed with certain subjects, rituals, or routines. The genetic contribution is that it seems to have a strong genetic basis and runs in families.

3. 50-60% for verbal abilities and 50% for spatial abilities, meaning that genetic differences explain at least half of the observed variation among the population.
Sarah Biddle and Caroline Thomson
1) 40%-66% is inherited, temperament is inborn characteristics and is often consistent though it may respond to special experiences or parental handling in the environment.
2) Schizophrenia is a disorder marked by the loss of contact with reality and has symptoms of hallucinations and delusions seems to have a strong genetic component.
3) the risk is ten times as great among siblings and offspring of schizophrenics. twin and adoption studies says this comes from sharing genes.
4)the disorder may originate in a lack of a chemical called reelin, which is present in the regions of the adult brain that handle higher mental functions such as language and problem solving.
5)The genetic contribution is between 63 and 85 percent
6)Autism is a disorder of the brain, characterized by lack social interaction, impaired communication and imagination, and repetitive, obsessive behavior.
7) autism affects an estimated 16 of every 10,000 people. It usually appears within the first 3 years of life.
8)The gender that it affects the most is boys
9)the genetic contribution is one likely candidate is a variant of a gene called HOXA1, which is involved in the development of the brain stem, the most primitive part of the brain.

Personality
1. Traits such as extraversion, neuroticism, conscientiouness, agreeableness, and openness to experience suggest a heritability of about 40%.
Studies have found that genetics have an influence on activity, sociability, and emotionality. A child's environment can affect personality by observing their parent's behavior and their surroundings.
Schizophrenia
1. A disorder marked by loss of contact with reality and by such symptoms as hallucinations and delusions.
2. The risk of schizophrenia is ten times as great among siblings and offspring of schizophrenics as among the general population.
3. Some studies suggest that this disease is caused by a lack of a chemical called reelin, which is present in the regions of the adult brain that handle higher mental functions.
4. The estimated genetic contribution is between 63 and 85 percent.
Autism
1. Pervasive developmental disorder of the brain characterized by normal social interaction, impared communication and imagination, and repetitive obsessive behaviors.
2. Autism affects an estimated 16 of every 10,000 people.
3. Autism mostly affects males.
4. An autistic child may fail to notice the emotional signals of others and often show repetitive or obsessive behavior.
5. Autism runs in families and has a strong genetic basis due to a variant of a gene called HOXA1, which is involved in the development of the brain stem.
1. Depending on the environment we grow up in we learn from what we see and it effects our personality. Heredity also effects our personality because we are born with certain traits but the environment influences them.
1. Schizophrenia is a disorder marked by loss of contact with reality and by such symptoms hallucinations and delusions, seems to have strong genetic component.
2. The risk of schizophrenia is 10 times as great amongst siblings and offspring of schizophrenia.
3.The cause of schizophrenia can be purely genetic, prenatal viral infections, people born in urban areas and in rural areas, birth complications and of exposure to infection during pregnancy and childhood.
4.The percentage is 63-85%.
1. Autism is a disorder of brain functioning. It's characterized by lack of normal social interaction.
2. Autism effect an estimate 16 of every 10 thousand people.
3. Autism effects boys the most.
4. An autism baby may fail to notice the emotional signals of others and may refuse to cuddle or make eye contact. An autism child may speak in a sing-song voice, pay little or no attention the the listener. Several autism children often show repetitive behaviors and are obsessed with certain subjects, rituals or routines.
5. Autism has no single cause but runs in families and seems to have strong genetic basis.
PERSONALITY
1. heritability (genes influencing traits): family, adoption, twin studies, concordance, canalization (limitation of expression). env: if predisposed to pollen, allergies may develop; traits don't show unless there is an interaction between heredity and environment. genetic & environmental influences act in the same direction; they reinforce eachother.
SCHIZOPHRENIA
1. mental disorder marked by lost contact with reality; symptoms: hallucinations and delusions.
2. riskier for siblings/offspring of schizophrenics. increased chances come from genes, not shared environment.
3. lack of REELIN (chemical). reelin helps to correctly position and align nerve cells in the developing brain. when the gene is defective, results may be misplacement of nerve cells, creating predisposition, or vulnerability, to schizophrenia.
4. 63-85%
AUTISM
1. pervasive development disorder of the brain, characterized by lack of normal social interaction, impaired communication and imagination, and repetitive, obsessive behaviors.
2. 16 of every 10,000 people.
3. male
4. repetitive behaviors, failure to notice emotional signals of others, refusal to cuddle or make eye contact, paying little or no attention, may perform unusual mental feats such as memorization, obsessed with certain subjects, rituals, or routines.
5. one likely candidate is a variant of a gene called HOXA1, which is involved in the development of the brain stem, the most primitive part of the brain.
INTELLIGENCE AND SOCIAL ACHIEVEMENT
1. adopted children's IQs are consistently closer to the IQs of their biological mothers compared to the IQs of their adoptive parents and siblings.
2. monozygotic twins' IQs are more similar than dizygotic twins' IQs.
3. 50-60% for verbal abilities. measured genetic intelligence increases with age. family environment influences younger children moreso than older.
Megan Ryan and Kayla Longshaw

5. Autism has no single cause but runs in families and seems to have a strong genetic basis. Several different genes may be involved in cases of varying symptoms and severity. One likely candidate is a variant of a gene called HOXAI, which is involved in the development of the brain stem. Autism results from genetic predisposition combined with an environmental assault.
Intelligence and School Achievement
1. Evidence of the role of heredity in intelligence has emerged from adoption and twin studies. Adopted children's IQs are consistently closer to the IQs of their biological mothers then to those of their adopted parents and siblings. The studies yield a consistent estimate of heritablity: 50-60% for verbal abilities and 50% for spacial abilities.

3. It affects the male gender the most.
4.Symptoms include failure to notice emotional signals of others and may refuse to cuddle or make eye contact, may speak in a sing song voice, paying little or no attention to the listener. Severely autistic children often show repetitive behaviors such as spinning, rocking,hand-flapping, and head-banging, and are obsessed with certain subjects, rituals, or routines.
5. The genetic contribution is several different genes are involved. One candidate is a variant of a gene called HOXA1, which is involved in the development in the brain stem.
Intelligence and School Achievement
1. Adoption studies have proven that either IQs are closer to the IQs of their biological mothers than those of their adopted parents.
2. Twin studies prove that identical twins are more alike in intelligence than fraternal twins.
