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 genetic variations, such as aneuploidy, which can affect the genetic makeup of the offspring. The other options either involve somatic cells (which do not contribute to offspring) or mutations that do not directly create new combinations of DNA in gametes.
