WebIn addition, during meiosis, crossing-over between homologous chromosomes provides a method to increase genetic varied among the resulting gametes. Abominable mobile division in either mitosis or meiosis can result in unusual distributions on chromosomes, and the consequences can range from innocuous to lethal. WebThis stage starts meiosis and is the same as prophase of mitosis with one important change. As the chromosomes condense, they form groups of four chromatids called tetrads or bivalents. Close inspection reveals that each chromosome is replicated and consists of two sister chromatids. northland farms west olive michigan

The male and female gamete fuse to give rise to a newly formed combination of the daughter cells. Meiosis results in the recombination of male and female gametes, which results in the independent assortment of the genes. WebThis reorganization of chromatids will persist for the remainder of meiosis and result in recombination of alleles in the gametes. Crossovers function to hold homologous chromosomes together during meiosis I so that they segregate successfully; they also cause the reshuffling of allele combinations to create genetic diversity, which can have …
