End of meiosis I (in daughter cells) o Chromosome #: 23 ( That is why Meiosis I is called as reduction division, reduction in chromosome number to half) o Chromatid #: 46. Meiosis II [2nd Cell Division] is similar to Mitosis. Prophase II. o Chromosome #: 23. WebThis results in 1/2 as many chromosomes per cell. The second division is meiosis II: this division is like mitosis; the number of chromosomes does not get reduced. The phases have the same names as those of mitosis.

WebPaired homologous chromosomes crossover while in synapsis, this happens during early prophase 1. By late prophase 1, the synaptonemal complex has disassembled and the homologues are only linked at places called chiasmata (singular, chiasma) where crossover occured. This all occurs before metaphase 1 begins. WebCytological examination of ZYP RNAi1-6 chromosome spreads revealed that AE development in early prophase was normal, but the majority of prophase I nuclei showed little or no chromosome alignment.
