Document Summary
Module 3. 1: genetic and evolutionary perspectives of behaviour. ~ behavioural genomics is the study of dna and the ways in which specific genes are related to behaviour. ~ the human genome project, which was completed in 2003, resulted in the identification of approximately 20 000 25 000 genes. ~behavioural genetics is the study of how genes and the environment influence behaviour. comparing people of different levels of relatedness, such as parents and their offspring, siblings, and unrelated individuals, and measuring resemblances for a specific trait of interest. Mono= comes from one eggs , share 100% of genes (identical twins) Di=come from two eggs, share 50% of genes (fraternal twins) ~longitudinal studies, studies that follow the same individuals for many years, often decades. Heritability of 0= genes do not contribute to differences in an individual trait. Heritability of 1. 0= genes account for all individual differences in a trait. ~ 6000 -7000 genomes are active in the brain.
