Each of these divides again by mitosis (the chromosomes splitting lengthwise), the half or haploid number remaining.Taboo and Genetics

The next stage is their separation to the haploid daughter-nuclei, which have resulted from the reduction process.Darwin and Modern Science

- A haploid organism or cell.
- Having a single set of each chromosome in a cell or cell nucleus. In most animals, only the gametes (reproductive cells) are haploid. Compare aneuploid diploid. See Note at mitosis.
