Why are strong muscles developed by exercise not directly passed to offspring?
Answer and explanation
Correct answer: Because it does not change genetic information in reproductive cells
The governing principle is the distinction between acquired traits and inherited traits. Exercise can enlarge or strengthen muscles during an individual’s lifetime, but this bodily change does not normally alter the DNA of sperm or eggs. Since offspring receive hereditary information through reproductive cells, the exercise-developed muscle is not directly transmitted. Option A is correct; B confuses tissue with chromosomes, C is scientifically false, and D is false because offspring inherit genes.
