WebMay 30, 2024 · How do meiosis contributes to genetic variation while mitosis does not? Assess how meiosis contributes to genetic variation, while mitosis does not. During meiosis, the independent assortment of the pairs of chromosomes and crossing over provide a large amount of genetic variation. Mitosis produces identical cells. WebSep 4, 2024 · Meiosis is a type of cell division in which the number of chromosomes is reduced by half. It occurs only in certain special cells of an organism. In mammals, …
WebThe process of meiosis is highly regulated. Many different molecules and proteins are responsible for regulating the steps of meiosis as they occur. If any mistakes occur during the replication of chromosomes, it may have drastically detrimental effects on the resulting offspring. Errors may also occur during chromosome segregation. 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.
WebJun 8, 2024 · Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an … WebAug 17, 2024 · How does meiosis contribute to genetic variation in a cell? Meiosis is recognized as a process that contributes to genetic variation. Here’s a brief overview: There are two divisions that occur during the entire process of meiosis, ending in haploid cells.
