Reassortment of chromatids

WebbSynapsis is the process in which homologous chromosomes carefully pair. The pairing allows for an orderly first division to send one chromosome from each pair to separate cells. The close association of the homologous chromosomes also allows for crossing over between non-sister chromatids (Fig.3). WebbIn replication, the DNA molecule is copied, and the two molecules are known as chromatids. During the later stages of cell division these chromatids separate …

WebbMeiosis I. Meiosis is preceded by an interphase consisting of G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase (the “first gap phase”) is focused on cell growth. During the S phase—the second phase of interphase—the cell copies or replicates the DNA of the chromosomes. WebbProduction of four diploid cells takes place after the cytokinesis of the cells having the two sets of the chromosomes. The DNA replication suppression between meiosis I and II involves the two divisions phase without the occurrence of S phase. 15.

WebbChromosomes segregate during Meiosis I and you might expect that all genes on a chromosome would be inherited as a unit. However, during prophase I homologous chromosomes pair up and become attached to one another. At this time, crossing over moves sections of DNA between homologous chromosomes and allows for independent …
