WitrynaThe heritability coefficient and, in fact, the whole quantitative structure that underlies it does not match up with our nature-nurture intuitions. We want to know how important the roles of genes and environment are to the development of a trait, but in focusing on what is considered important, perhaps we are emphasizing the wrong thing. WitrynaThe missing heritability problem is the fact that single genetic variations cannot account for much of the heritability of diseases, behaviors, and other phenotypes.This is a problem that has significant implications for medicine, since a person's susceptibility to disease may depend more on the combined effect of all the genes in the background … WitrynaHowever, heritability estimates depend on the population under study, diagnostic instruments, and study designs that each has its inherent assumptions, strengths, and biases. We aim to test the homogeneity in heritability estimates between two powerful, and state of the art study designs for eight psychiatric disorders. triple helix industries
