Question

Quizplus · Accepted Answer

Professor Glossner proposes that the heritability of temperament is .80, which means that 80% of the variation in temperament can be attributed to genetic factors. Therefore, choice A - "A large portion of temperament is determined by genetics" - is the correct answer. Choice B, "A large portion of temperament is determined by environment," is incorrect because the heritability estimate suggests that genetics play a larger role than environment in shaping temperament. Choice C, "Eighty percent of temperament is determined by the X chromosome" and choice D, "Twenty percent of temperament is determined by the X chromosome," are both incorrect because the heritability estimate does not specifically refer to the role of the X chromosome in determining temperament.
