Correlations of which of the following are needed to compute heritability, nonshared environmental effects, and shared environmental effects for a trait?

Question

Quizplus · Accepted Answer

To compute heritability, nonshared environmental effects, and shared environmental effects for a trait, correlations between identical twins raised together and fraternal twins raised together are needed. This is because identical twins share 100% of their genes, while fraternal twins share, on average, 50% of their genes. Comparing these correlations allows researchers to parse out the effects of genetics, shared environment, and nonshared environment on a trait.
