Homologous chromosomes failing to separate during meiosis.

The best example that would likely result in new combinations of DNA in an individual's offspring is:
Homologous chromosomes failing to separate during meiosis.
This scenario can lead to gametes with an abnormal number of chromosomes, which can result in offspring with genetic variations if fertilization occurs with a normal gamete. In contrast, the other options involve processes that do not lead directly to the mixing of genetic material between homologous chromosomes or offspring.
