Chromosome separation
WebMay 26, 2000 · This temporal separation forms the basis for the cell cycle's partition into four phases—G 1, S, G 2, and M—and it has played a central role in the evolution of eukaryotic organisms. Meiosis, during which two rounds of chromosome segregation follow a single round of duplication, requires separable S and M phases. WebWhen genes are close together on a chromosome, the alleles on the same chromosome tend to be inherited as a unit more frequently than not. Such genes do not display independent assortment and are said to be linked. …
