Document Summary

Genetic predisposition: it is an increased likelihood of developing particular disease based on a person"s genetic makeup. Phenotype- the outward physical manifestation of our genotype which is internally coded, inheritable information* Genetics ingredients + environment = product. Heritability- amount of variability in a trait that is attributed to hereditary influence. Genotype- inherited genes: (genotype) inherited genes are expressed through (phenotype) observable characteristics and behaviours. Sandra scarr & kathleen mccartney: theory of genotype environment effects, the person"s genotype drives experience. Passive: occurs when biological parents raise child, decrease in influence over time, inseparable effects of genetics and environment, promotes similarities in siblings. Evocative: affect behaviour of others in environment, child"s genotype elicits responses from others, presumably remains constant, unshared environment increases differences among siblings. Active: actively select comfortable environment, different genotypes attracted to different environments, results in different experiences, also referred to as niche-picking, increases in influence over time, children in same home may become increasingly different.
