Document Summary

Behaviour genetics: study of relative power and limits genetic and environmental influences on behaviour. Environment: every non-genetic influence, from prenatal nutrition to people and things around us. Genome: complete instructions for making an organism, consisting of all genetic material in that organisms chromosomes. Identical: develop from single fertilized egg that splits in two, genetically identical, same sex only, don"t always have same number of copies of genes. This explains why one twin may be at higher risk for certain illnesses: usually share same placenta but some don"t. Identical twins are more likely to have similar personality traits than fraternal twins: experiences do not account for similarities, twin dressed identically are not more similar than those not dressed similarly, white people have more twins. Separated twins: similar even through they were separated at birth, less similar if separated at birth then if raised together, still separated identical twins are more alike than if they were fraternal, share appearance, emotional response.
