Why is an offspring not exactly identical even when it resembles its parents?
Answer and explanation
Correct answer: Because offspring receives genetic information from both parents
An offspring resembles its parents because it inherits chromosomes and genes from them. However, sexual reproduction combines one set of genetic information from each parent in a new arrangement, and recombination can produce differences. Therefore resemblance and variation occur together, making option A the best answer. Chromosomes and gametes are essential, so options B and D are incorrect; food alone does not determine all traits.
