WebQuestion: Why are comparisons between monozygotic and dizygotic twins useful for calculating broad-sense heritability? A)Monozygotic twins vs. dizygotic twins are never part of the same family, so environment is randomized. B)The twins are always raised in different environments, so you can compare them to figure out the role of genetics. WebAlthough narrow-sense heritability is most often reported in these expanded studies, the difference between broad-sense and narrow-sense heritability is often small when it is measured.
