If your parent"s vote conservative, you may vote conservative. Parent offspring correlations have been assumed by sssm as evidence that parenting is important. Cannot dissociate genetic and environmental contributions: this could be environmental (shared home environment) or shared genes. The amount of variation in a specific population that is due to variation in genes. Heritability is always specific to a population. Can be measured by selective breeding experiments, look at family trees and look parent-offspring correlations, twin studies (galton: comparing identical twins to fraternal twins. Monozygotic twins are more similar to each other than dizygotic twins (substantial heritability) Breaking it down by: shared environment, shared genes, and unique environment: shared genes and unique environments usually explain most things (shared environment does not show a lot) Warning: term heritability is often misused does not indicate a trait is x% genetic: heritability means the proportion of variance accounted for by genetic variation.
