Answer: Option B) diversity of the offspring produced
Step-by-step explanation:
Since sexual reproduction involves the fusion of male and female gametes formed by meiosis, and meiosis involves the formation of gametes that that undergone crossing over or exchange of genetic material between sister chromatids, hence, the resulting sex cells are usually different in genetic composition from the individual parents.
Thus, the crossing over of genetic material in sexual reproduction allows new species to emerge over time.
