A boy develops strong muscles through exercise. Why will this trait not pass directly to his children?
Answer and explanation
Correct answer: Because it is an acquired trait and does not change the genetic information of reproductive cells
Muscle development caused by exercise is an acquired modification that occurs in body tissues during an individual’s lifetime. It does not ordinarily change the DNA information carried by that person’s reproductive cells, so it is not transmitted directly to offspring. Inherited traits arise from genetic information passed through gametes. Therefore option A is correct; muscles are tissues, not genes, and children do have chromosomes.
