WebDuring meiosis I, however, the parent, diploid (2n), germ cells are divided to create two haploid (n) daughter cells. This means that in nematodes, the parent cells will contain 4 total chromosomes, but the daughter cells will only have 2. Important terminology here is homologous pairs chromosomes, or homologues. WebJul 17, 2024 · Meiosis is a two-part cell division process that produces sex cells with one half the number of chromosomes as the parent cell.

This stage is characterized by the movement of chromosomes to both poles of a meiotic cell via a microtubule network known as the spindle apparatus. This mechanism separates homologous chromosomes into two separate groups. In anaphase I, the …
