It promotes genetic diversity among offspring. During crossing over, homologous chromosomes exchange segments of DNA, which leads to the shuffling of genetic material. This result in new combinations of genes and increases genetic variation in potential offspring.
It also plays a role in creating more stable chromosomes. Crossing over helps to repair any DNA damage or breaks that may have occurred during the early stages of meiosis, ensuring that both chromosomes in each pair remain intact and functional.
Crossing over does not play a direct role in reducing the chromosome number. This reduction occurs during the subsequent stages of meiosis, specifically during the separation of homologous chromosomes in Anaphase I and the separation of sister chromatids in Anaphase II.
Lastly, crossing over does not directly involve the division of the cell membrane. The division of the cell membrane occurs during cytokinesis, which takes place after meiosis is completed.
