Ploidy
Ploidy is the number of sets of chromosomes in the nucleus of a biological cell. Normally a gamete carries a full set of chromosomes that includes a single copy of each gene, as aneuploidy generally leads to severe genetic disease in the offspring. The haploid number is the number of chromosomes in a gamete. Two gametes form a diploid zygote with twice this number i.e. two copies of autosomal chromosomes. However, the sex chromosomes of diploid cells, which are subject to sex linkage, may be considered as haploid chromosomes. Technically, ploidy is a description of a nucleus. Though at times authors may report the total ploidy of all nuclei present within the cell membrane of a syncytium, usually the ploidy of the nuclei present will be described. For example, a fungal dikaryon with two haploid nuclei is distinguished from the diploid in which the chromosomes share a nucleus and can be shuffled together. Nonetheless, because in most situations there is only one nucleus, it is commonplace to speak of the ploidy of a cell. Cells are described according to the number of sets present: haploid, diploid, triploid, tetraploid, pentaploid, hexaploid, heptaploid or septaploid, octoploid, nonaploid, decaploid, undecaploid, dodecaploid, tridecaploid, tetradecaploid etc. Some higher ploidies include hexadecaploid, dotriacontaploid, and tetrahexacontaploid, though Greek terminology may be set aside for readability in cases of higher ploidy. Polytene chromosomes of plants and fruit flies can be 1024-ploid. Ploidy of systems such as the salivary gland, elaiosome, endosperm, and trophoblast can exceed this, up to 1048576-ploid in the silk glands of the commercial silkworm Bombyx mori. The generic term polyploid is frequently used to describe cells with three or more sets of chromosomes.
