Paradoxically, reduced immunostaining signals of meiosis-specific cohesin, including the kleisin Rec8, were observed on chromosomes during late prophase-I of budding yeast. It was assumed that, unlike the situation in mitosis, chromosome arms retain cohesion prior to onset of anaphase-I. Illustration showing the nine stages of meiosis.Sister chromatid cohesion on chromosome arms is essential for the segregation of homologous chromosomes during meiosis I while it is dispensable for sister chromatid separation during mitosis. in females, one of the cells is an egg cell while the other three are polar bodies (small cells that do not develop into eggs).in males, these four cells are all sperm cells.Once cytokinesis is complete there are four granddaughter cells, each with half a set of chromosomes (haploid):.This is the last phase of meiosis, however cell division is not complete without another round of cytokinesis.A membrane forms around each set of chromosomes to create two new cell nuclei.
