Document Summary

Locus/loci: the location of a gene on the chromosome. Homozygous: when both genes at the locus are the same. Heterozygous: when the genes at the locus are different. Dominant gene: the allele for brown eye colour is dominant to the gene of blue eye colour. Recessive gene: the allele for blue eye colour is recessive to the gene of brown eye colour and will be overpowered by a single dominant gene. Concordance: the degree of similarity for twins. Single gene traits: some behaviours are dependent on one single gene and a mutation of this gene can cause mild to severe deficits. Polygenic: most behaviours and disease states are caused by a mutation across many genes. Developmental psychology: concerned with the environmental variance component, the prenatal and postnatal environmental influences that affect individuals during their lifetime. Evolutionary psychology: concerned with the design of human nature, all human behavioural characteristics that are the product of natural selection in ancestral environments.
