Mitosis Colchicine

Mitosis Colchacinin Mitosis Colchacinin is a simple and one of the first and therefore simplest types of meiosis. Colchacini mitoses contain such features as straight arms, boundary exchange of chromosomes (sometimes), synchronous interkinesis, some autonomy of sister chromatids, and the especially important influence of the Col genes on it and on the nature of the formation of intervalent exchange arms.

It is also the only type of meiosis that has been analyzed by rapid genetic sequencing methods, which have proven useful for studying the genetics of seed and leaf color in maize. This would make it much easier to study chromosome segregation and identify color genes in all chromosomal regions and on each chromosome.

In the analysis of mutations and studies of the causes of inbreeding, it was found that c-Mitoses carry with them both positive and negative consequences in the hosts, including damage to the endosperm, impaired pollen development, the endosperm after the second germination/ground seeds was defective, the length of the cytoplasm was increased, The formation of membrane invagination was impaired, and the reproductive cells were bulged. All signs, although associated with health problems (gametopathy), are not dominant, and a normal-sized gamete of the opposite sex may also be visible.

It is also interesting to note that when Col8 is mutated in C. cristatum, Colchacin does not progress to mitosis; Probably, the suppressive effect of the gene inducing exit from meiosis a is a property of homologous chromosomes to chromo-13 and the 3rd chromosome in the mutational homologous region Col8-C9.
