The latest parasexual years was initially classified during the An effective
FIG.8. Mitotic crossing-more and you can homozygosity. A mix-more associated with two of the four chromatids of an effective homologous couples off chromosomes results in a good rearrangement from alleles between them chromosomes. At the second mitotic office, brand new chromosomes can be orientate on their own in 2 possible means, causing two possible methods out of chromatid separation: (a) step 1 and you may 4 splitting up away from 2 and you can step 3, or (b) step 1 and step three separating out of dos and 4. One among these a couple it is possible to settings, (b), results in homozygosity of the circumstances out of mitosis getting alleles in the one locus (B/b) distal until regarding mitotic crossing-over.
