How does the process of meiosis contribute to genetic diversity

How does the process of meiosis contribute to genetic diversity and the evolution of species? Meiosis is a specialized form of cell division that occurs in sexually reproducing organisms, resulting in the formation of gametes (sperm and egg cells) with half the number of chromosomes as the parent cell. One of the key features of meiosis is genetic recombination, wherein homologous chromosomes exchange genetic material during crossing over in Prophase I. This shuffling of genetic information between chromosomes generates unique combinations of alleles in the gametes, increasing genetic diversity within a population. Furthermore, during the subsequent stages of meiosis, such as Metaphase I and Anaphase I, the random assortment of homologous chromosomes further contributes to the variability of genetic traits in offspring. The accumulation of genetic diversity through meiosis provides the raw material for natural selection to act upon, driving the evolution of species over time.
