What might explain the difference in heritability coefficients between twin and non-twin studies?
A) increased measurement error in non-twin studies
B) the presence of interactive genetic effects
C) the greater statistical power of twin studies
D) the rarity of non-twin studies

Question

Quizplus · Accepted Answer

The presence of interactive genetic effects can lead to differences in heritability coefficients between twin and non-twin studies, as twin studies can better account for these interactions due to the genetic similarities between twins.
