The assortment of homologous chromosomes during meiosis is random and generates genetic variation, the raw material for evolution.
During metaphase I of meiosis, homologous chromosomes are lined up at the equator plate of the cell in order to be separated (assorted) in anaphase I.
The separation of homologous chromosomes during meiosis I is random. Daughter cells receive unique gene combinations from an original parent cell.
Subsequently, haploid cells got from two successive meiotic divisions fuse during fecundation to form a diploid (2n) zygote.
During prophase I, non-sister chromatids interchange genetic material by a process known as recombination. This genetic process also increases genetic variation in daughter cells.
In conclusion, the assortment of homologous chromosomes during meiosis is random and generates genetic variation.
