Crossover chromosome phase
WebMay 26, 2024 · The formation of crossovers between homologous chromosomes is key to sexual reproduction. In most species, crossovers are spaced further apart than would be … WebAt a given chiasma, an exchange of genetic material can occur between both chromatids, what is called a chromosomal crossover, but this is much more frequent during meiosis than mitosis. [1] In meiosis, absence of a chiasma generally results in improper chromosomal segregation and aneuploidy. [2]
