haploid (not comparable)

2. (genetics, loosely) Having the number of chromosomes that a typical gamete has (in the given organism), namely, half the number that a typical somatic cell has (in the given organism).

   Hyponyms: monoploid (1 set), diploid (2 sets)

   Coordinate terms: euploid; aneuploid, nonaneuploid; (more than 2) polyploid (as follows), triploid (3), tetraploid (4), pentaploid (5), hexaploid (6), heptaploid (7)

   2. (genetics, strictly) Having a single set of unpaired chromosomes (which is the number that a typical gamete has in many organisms although not all).

      Synonym: monoploid

      Hyponyms: gynohaploid, allohaploid, polyhaploid

      Coordinate terms: euploid; aneuploid, nonaneuploid; diploid (2); (more than 2) polyploid (as follows), triploid (3), tetraploid (4), pentaploid (5), hexaploid (6), heptaploid (7)

      Examples of haploid cells are prokaryotes and the gametes of eukaryotes.

        It has been shown, however, that triploid forms producing diploid gametes in one sex and haploid ones in the other sex can act as a stepping stone towards tetraploidization (triploid bridge; ).

haploid (plural haploids)

1. A cell which is haploid.

     In teleosts, double haploids (DHs) induced by mitogynogenesis are often sterile.

2. An organism, such as a fungus, with haploid cells.
