Meiosis is the production of four genetically diverse haploid daughter cells from one diploid parent cell. Meiosis can only occur in eukaryotic organisms. It is preceded by interphase, specifically the G phase of interphase.

It is a process of chromosomal reduction, which means that a diploid cell (this means a cell with two complete and identical chromosome … Ver mais Before meiosis, the chromosomes in the nucleus of the cell replicate to produce double the amount of chromosomal material. After chromosomal replication, chromosomes separate into sister chromatids. This is … Ver mais After Interphase I meiosis I occurs after Interphase I, where proteins are grown in G phase and chromosomes are replicated in S phase. Following … Ver mais Meiosis II may begin with interkinesis or interphase II. This differs from interphase I in that no S phase occurs, as the DNAhas already been replicated.
