WebTo summarize, we learned that sexual reproduction occurs when two haploid gametes fuse together in fertilization, creating a diploid offspring with homologous chromosome pairs. We also learned that the patterns of chromosome inheritance during sexual reproduction lead to genetic variation in families and populations. WebOct 15, 2024 · 13. The answer is clearly and unequivocally (E). Mutations introduce genetic variation. Period. As for (C), mutations are certainly reversible. If you can mutate a base to another base, you can mutate that base back to its original base. This is a simple fact of chemistry.
