In sexual reproduction, the variation among offspring, and the fact that they are genetically different from their parents, is due to which of the following?

Question

Quizplus · Accepted Answer

All of the above contribute to genetic variability in sexual reproduction. The random process of fertilization leads to different combinations of the genetic material from each parent. The random alignment of homologues during meiosis I and the resulting crossing over during meiosis I also shuffle the genetic material, leading to further variation among offspring.
