Why does cutting the tail of a mouse not produce tailless offspring?

Answer and explanation

Correct answer: Because it is an acquired change

The governing concept is that only heritable genetic changes in reproductive cells are normally transmitted to offspring. Cutting a mouse’s tail changes the body during its lifetime, but it does not alter the DNA of the sperm or egg cells that form the next generation. Therefore option A is correct. The cutting does not change genes in the required hereditary sense, a tail is not a chromosome, and offspring are living organisms rather than fossils.
