Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to ...

so as to maintain genomic ploidy (number of chromosomes) from one generation to the next. The cell's DNA is replicated in S phase and segregated in M phase (mitosis). In somatic cells, these ...

To return from a diploid stage to a haploid stage, meiosis must occur. In regard to changes of ploidy, there are 3 types of cycles: The cycles differ in when mitosis (growth) occurs. Zygotic meiosis ...

Meiosis reduces ploidy by following one round of DNA replication with two rounds of chromosome segregation (Meiosis I and Meiosis II respectively). In Meiosis I homologous chromosomes separate, which ...
