WebApr 8, 2024 · Complete answer: Meiosis also induces genetic variation by means of the recombination process. Later, as two gametes combine during fertilization, this variation is increased even more, thereby producing offspring with special DNA combinations. WebNov 6, 2024 · In meiosis, two events are responsible to increase genetic diversity. First is the crossing over and second is independent assortment. In the prophase of meiosis, I, the homologous chromosomes make pairs and they attach by their alleles of the same genes. After that, they exchange their genes by crossing over.

Genetic Variation in Meiosis Concept, Function & Significance

WebAug 19, 2016 · Genetic variation is increased by sexual reproduction. Explanation: In sexual reproduction male and female gametes come together. Gametes are formed as a result of meiosis. When fertilization occurs there is shuffling of genes. This shuffling of genes causes genetic variation. Answer link WebMay 29, 2024 · Meiosis also produces genetic variation by way of Genetic variation is increased by meiosis Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I. first weber omro wi
