| "Myrmecia pilosula, an Ant with Only One Pair of Chromosomes" | The chromosome sets may be from the same species or from closely related species |
|---|---|
| If a haploid set consists of two sets, it must be of a tetraploid four sets species | Etymology [ ] The term ploidy is a from haploidy and diploidy |
Unlike euploidy, aneuploid karyotypes will not be a multiple of the haploid number.
7| However, in many situations somatic cells double their copy number by means of as an aspect of | Euploid would consequentially be a multiple of the , which in humans is 23 |

| Haplodiploidy [ ] Ploidy can also vary between individuals of the same species or at different stages of the | Because in most situations there is only one nucleus per cell, it is commonplace to speak of the ploidy of a cell, but in cases in which there is more than one nucleus per cell, more specific definitions are required when ploidy is discussed |

21| An organism whose somatic cells are tetraploid four sets of chromosomes , for example, will produce gametes by meiosis that contain two sets of chromosomes | Examples include , , and |

| Ploidy of systems such as the , , , and can exceed this, up to 1048576-ploid in the silk glands of the commercial silkworm | A human cell with one extra set of the 23 normal chromosomes functionally triploid would be considered euploid |
Authors may at times report the total combined ploidy of all nuclei present within the cell membrane of a , though usually the ploidy of each nucleus is described individually.
