Why do acquired traits usually not pass to offspring?

Answer and explanation

Correct answer: Because they may remain limited to body cells and do not change genes in reproductive cells.

The governing distinction is between somatic changes acquired during life and hereditary information carried by reproductive cells. Exercise, scars or learned abilities may alter body cells or behaviour, but they usually do not change the genes in sperm or eggs. Without a change in reproductive-cell DNA, the trait is not transmitted genetically. Option B is correct; usefulness, fossils and dominance do not explain inheritance.
