In preparation for meiosis, a germ cell goes through interphase, during which the entire cell (including the genetic material contained in the nucleus) undergoes replication. WebMeiosis is a type of cell division that results in the creation of four daughter cells from a single parent cell. The process is called mitosis.

If those two cells … WebThere are several points during sexual reproduction at which genetic variation can increase. In meiosis I, crossing over during prophase and independent assortment during anaphase creates sets of chromosomes with new combinations of alleles. Genetic variation is also introduced by random fertilization of the gametes produced by meiosis. diamond wood sutton boningtonWebAs a result of the independent assortment, the meiosis process causes genetic variation. As a result, there are four primary forms of meiosis that result in genetic variation. During meiosis, it involves 1) mutation, 2) random fertilization, 3) random mating among organisms, and 4) crossing over between homologous chromosomes with chromatids. cistern\u0027s i
