Document Summary

Heredity involves passing along genes through reproduction: genes" variation are either dominant or recessive, the genome represents the genotype and the observable characteristics are the phenotype, many characteristics are polygenic. Genotypic variation is created by sexual reproduction: half of each chromosome comes from each parent and the two halves are joined randomly, there is enormous potential variation in the resulting zygote"s genome, mutations also give rise to variations. Genes affect behaviour: behavioural genetics methods, heritability, twin studies, research on adoptees, and other investigations of hereditary and genetic influence provide insight into heritability, behavioural geneticists can quantify the similarity and variations in a population"s shared characteristics. Genetics counseling: disabilites, grounds for abortion, pre-condition for marriage/partnerships, people knowing all the issues before marriage, informally this happens but if its interrogated. Insurability: i. e. genetic form of breast cancer that you can find out.
