haploid
hap·loid / ˈhapˌloid/ Genetics • adj. (of a cell or nucleus) having a single set of unpaired chromosomes. Compare with diploid. ∎ (of an organism or part) composed of haploid cells.• n. a haploid organism or cell.DERIVATIVES: hap·loi·dy n.
haploid
haploid Term describing a cell that has only one member of each chromosome pair. All human cells except gametes are diploid, having 46 chromosomes. Gametes are haploid, having 23 chromosomes. The body cells of many lower organisms, including many algae and single-celled organisms, are haploid. See also alternation of generations; meiosis
haploid
haploid Applied to a cell nucleus that contains one of each type of chromosome, i.e. one set of chromosomes, designated n. Gametes are haploid, in contrast with most somatic cells, which usually have some multiple of this number, usually 2n (diploid), but sometimes 3n (triploid), 4n (tetraploid), or many-n (polyploid). A haploid cell thus has only one chromosome set, and a haploid organism contains only haploid cells.

haploid
haploid Applied to the number of chromosomes in a gamete and conventionally symbolized by n. In somatic (i.e. non-sex) cells, the number of chromosomes is usually some multiple of this number (e.g. diploid 2n, triploid 3n, or tetraploid 4n, but sometimes polyploid many-n).
