Why does sexual reproduction produce more variation in offspring?
Answer and explanation
Correct answer: Because genes from both parents form new combinations
Sexual reproduction combines genetic material from two parents. During meiosis, chromosomes and alleles are assorted and recombined, and fertilisation joins one gamete from each parent in a new combination. Consequently, offspring usually differ from both parents and from one another, providing variation on which selection can act. Option B correctly describes this process. A describes asexual reproduction, C is biologically false, and D is the opposite of the expected result.
