Twin studies and studies of adopted children allow behavioral geneticists to examine the relative contributions of genes and environment in the development of various behavioral traits. They do not indicate which factor "wins" over the other, but rather how both factors work together to shape behavior. The polygenic nature of inheritance refers to the fact that many traits are influenced by multiple genes, not just one.
