Chromosome count during meiosis
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.
