Answer 1

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 scenario can lead to gametes with an abnormal number of chromosomes, which can result in genetic variation when these gametes combine during fertilization. The other examples involve mutations or processes that occur in somatic cells and do not affect the gametes that contribute to offspring.
