Answer 1

The response that would likely result in new combinations of DNA in an individual's offspring is:

**Homologous chromosomes failing to separate during meiosis.**

This process is known as nondisjunction, which can lead to gametes with an incorrect number of chromosomes. If such a gamete participates in fertilization, it can result in offspring with unusual genetic combinations, potentially leading to genetic disorders or different phenotypes.
