The example that would likely result in new combinations of DNA in an individual's offspring is:
**Homologous chromosomes failing to separate during meiosis.**
When homologous chromosomes fail to separate, it can lead to gametes with an abnormal number of chromosomes, which can result in genetic variations in the offspring when these gametes combine during fertilization. The other examples listed do not involve meiosis or the formation of gametes, and therefore, they do not directly contribute to new combinations of DNA in offspring.
