Cytokinesis … WebIn meiosis 1, the number of chromosomes is reduced by one-half and for this reason, it is called reduction division. Meiosis 2 results in separation the sister chromatids and for this reason, it is known as equatorial division. Each of the two meiotic divisions is divided into interphase, prophase, metaphase, anaphase and telophase.

WebEine besonders wichtige Funktion der Metaphase besteht in der Überprüfung (Checkpoint) und Überwachung der von den Polen ausgehenden Spindelfasern (Mikrotubuli). Es muss sichergestellt sein, dass die Mikrotubuli mit dem jeweils „richtigen“ Centromer verbunden sind. Hierdurch wird erreicht, dass die beiden Chromosomensätze, die sich ...
WebMeiosis is the process in which a single cell divides twice to form four haploid daughter cells. These cells are the gametes – sperms in males and egg in females. The process of meiosis is divided into 2 stages. Each stage is subdivided into several phases.
