Document Summary

Module 3. 1: nature, behaviour genetics and evolutionary psychology innate constraints on behaviour. Behaviour genetics individual differences [due to genetic differences] Mutations not differentially affected by natural selection. Mutations that conferred a reproductive advantage to all. Phenotype: observable characteristics chromosomes: 23 pairs total. Autosomes: 22 pairs, same in m and f sex: 1 pair, xx or xy. Dominant: one gene sufficient recessive: both genes necessary. One approach: identify a specific behavioural [phenotypic] abnormality look for a corresponding genotypic abnormality. Affected ke adults learned to compensate by memorizing words. E. x. open mouth wide and stick tongue out language. 53% ke; less than 3% of the population single gene. Affected children only had one affected finding the mutated gene parent. Genome scan of affected and unaffected ke family members. Pointed to a broad locus on chromosome 7. Break in chromosome 7 in the middle of the. Analyze foxp2 in affected ke revealed mutation interpreting gene-behaviour link.
