Why are offspring formed by sexual reproduction not exactly identical to their parents?
Answer and explanation
Correct answer: Because a new combination of genetic material comes from both mother and father
The governing concept is genetic recombination in sexual reproduction. The offspring receives genetic material from two parents, and the combination of alleles is newly formed rather than copied from only one parent. Meiosis and the random union of gametes contribute to variation, so offspring resemble their parents while showing differences. Option A is correct. Options B, C, and D are wrong because offspring possess genetic material from both parents, not none or just one parent.
