Meiosis exchange of genetic material

WebDuring meiosis, cells divide into four genetically unique daughter cells, each with half the number of chromosomes as the original parent cell. This is accomplished through two rounds of cell division, known as meiosis I and meiosis II. WebThe first theory rests upon the idea that meiosis evolved as another method of DNA repair, and thus crossing-over is a novel way to replace possibly damaged sections of DNA. …
