Imagine that researchers estimated the heritability score for trait W to be 45%. Which statement is a CORRECT interpretation of this estimate?

Question

Quizplus · Accepted Answer

The heritability score of 45% means that the variation in trait W within an entire population is 45% due to genetic factors. It does not imply that differences between racial groups or an individual's specific level of trait W are solely determined by genetics. Option A is incorrect because it implies that the heritability score explains differences between racial groups (which is not necessarily true) rather than the proportion of variation within the population. Option B is incorrect because it suggests that an individual's level of trait W is solely determined by genetics (which is also not necessarily true). Option D is incorrect because not all of the statements are correct interpretations of the estimate.
