If an organism gets a scar during its life why is the same scar not passed to its offspring?
Answer and explanation
Correct answer: Because it does not change the genetic material of reproductive cells
A scar is an acquired characteristic produced by injury during an individual’s lifetime. It generally affects somatic, or body, cells and does not alter the DNA of the germ cells that form eggs or sperm. Since hereditary information is transmitted through germ cells, the scar is not normally inherited by offspring. Therefore option A is correct; dominance, absence of chromosomes, and fossilisation are unrelated explanations.
