Question

Quizplus · Accepted Answer

A heritability of 50 percent means that genetic and environmental factors contribute equally to the disorder. It does not mean that half of the people who suffer from the disorder have a genetically caused disorder or that half of the children of carriers will actually develop the disorder. It also does not suggest that geneticists have identified half of the genes responsible for the disorder. Heritability only refers to the extent to which genetic differences among individuals contribute to differences in a trait or disorder.
