Correct answer: (A) Parents — According to Galton, only fifty percent of heredity is due to the parents, so that is the answer.
Explanation
★According to Galton, only fifty percent of heredity is due to the parents, so that is the answer.
★Galton's law of ancestral heredity traces inheritance back through the line of ancestors.
★It holds that the two parents together contribute about one half of a person's heredity.
★The remaining share is spread among the grandparents, great-grandparents and earlier ancestors.
★So the parents alone do not account for all of heredity, only about half of it.
★Since Galton assigns the parents fifty percent, the answer is the parents.
