Question

Quizplus · Accepted Answer

The mechanism for the production of genetic recombinants is crossing over and independent assortment during meiosis. Crossing over occurs during prophase I of meiosis where homologous chromosomes exchange corresponding segments of DNA. Independent assortment occurs during metaphase I when homologous chromosome pairs line up randomly on the equator of the cell. Together, these processes result in the production of genetically unique gametes that can then combine during fertilization to produce a genetically diverse offspring.
