Why are traits acquired during a lifetime generally not passed to offspring?
Answer and explanation
Correct answer: Because they do not change the genetic material of reproductive cells
Inheritance depends on genetic information carried in reproductive cells, such as sperm and eggs. A change acquired during life, such as a scar or increased muscle size from exercise, usually affects body cells but does not alter the DNA of the reproductive cells. It therefore is not normally transmitted to offspring. Option A states this principle; dominance, plant restriction, and chromosome doubling are unrelated explanations.
