WebThese four daughter cells only have half the number of chromosomes of the parent cell – they are haploid. Meiosis produces our sex cells or gametes (eggs in females and sperm in males). Meiosis can be divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II ... WebProphase I is further divided into sub-stages: Leptotene: In this stage, the initiation of chromosome condensation takes place and it attains a composite form. Zygotene: In this, the homologous chromosomes pairs, the process is called chromosomal synapsis. It is followed by the generation of a composite composition called the synaptonemal complex.

WebThe second meiotic division then separates the two sister chromatids from each other. Consequently, each of the four cells produced by meiosis has a single (haploid) copy of each chromosome. The first meiotic division … WebDuring mitosis the sister chromatids separate and go to opposite ends of the dividing cell. Mitosis ends with 2 identical cells, each with 2N chromosomes and 2X DNA content. All eukaryotic cells replicate via mitosis, except germline cells that undergo meiosis (see below) to produce gametes (eggs and sperm).
