The example that would likely result in new combinations of DNA in an individual's offspring is:
**Homologous chromosomes failing to separate during meiosis.**
This failure can lead to aneuploidy, where gametes may end up with extra or missing chromosomes, potentially leading to offspring with unique genetic combinations. The other options either involve mutations in somatic cells or processes that do not result in heritable genetic variation.
