Why will cutting the tails of mice for many generations not produce tailless offspring?
Answer and explanation
Correct answer: Because cutting the tail does not change hereditary information in gametes
Cutting a mouse's tail is a physical change acquired during its lifetime. It affects the body cells and does not normally alter the genes in the sperm or eggs that form the next generation. Consequently, the offspring inherit the genes for normal tail development and are not born tailless merely because parental tails were cut. Therefore option A is correct; B, C, and D do not explain heredity.
