Document Summary

Gene: a sequence of dna (or rna) that encodes the production of some gene product. Genome: the complete set of genes an organism possesses. These genes are located on 23 pairs of chromosomes (22 pairs of autosomes & 1 pair of sex chromosomes) We inherit 1 set of each pair from our mother & 1 set from our father. The scientific study of the nature & origins of individual differences in behaviour using genetic methods. There are 3 main goals of behavioural genetics to determine what percentage of individual differences can be attributed to genetic differences versus environmental differe. To determine the ways in which genes and environment interact and correlate with each other. To determine precisely where in the environment the effects are taking place. Heritability is a statistic that refers to the proportion of observed variance in a population of individuals that can be accounte. The proportion of phenotypic variance that is attributed to genetic variance.
