haploid

 [hap´loid]
having half the number of chromosomes characteristically found in the somatic (diploid) cells of an organism; typical of the gametes of a species whose union restores the diploid number.

hap·loid

(hap'loyd),
Denoting the number of chromosomes in sperm or ova, which is half the number in somatic (diploid) cells; the haploid number in normal human beings is 23.
Synonym(s): monoploid
[G. haplos, simple, + eidos, appearance]

haploid

1. having half the number of chromosomes characteristically found in the somatic (diploid) cells of an organism; typical of the gametes of a species whose union restores the diploid number.
2. an individual or cell having only one member of each pair of homologous chromosomes.

haploid

(hăp′loid′)
adj.
Having a single set of unpaired chromosomes, as in a germ cell, such as an egg or sperm, or in a moss plant or a drone bee.

Etymology: Gk, haploos, single, eidos, form
having only one complete set of nonhomologous chromosomes. Also monoploid, monoploidic. haploidy, n.

haploid

Genetics adjective Referring to:
1. A normal chromosome complement–expressed as n.
2. A cell with only one copy of each chromosome type–ie, half the number of chromosomes present in other cells; gametes–ie, sperm and ova are haploid. See Chromosome, Diploid, Polypoid, Prokaryote.

hap·loid

(hap'loyd)
Denoting the number of chromosomes in sperm or an oocyte, which is half the number in somatic (diploid) cells; the haploid number in normal human beings is 23.
[G. haplos, simple, + eidos, appearance]

haploid

Having half the number of chromosomes present in a normal body cell. The germ cells, the sperms and eggs (ova) are haploid, so that, on fusion, the full (DIPLOID) number is made up. From the Greek haploeides , single.

haploid

  1. (of a cell nucleus) containing one of each type of chromosome.
  2. a haploid organism in which the main life stage has cell nuclei with one of each type of chromosome, written as ‘n’. Such organisms (e.g. fungi, many algae) usually have a brief DIPLOID (2) phase (2n), returning to the haploid state via MEIOSIS. See ALTERNATION OF GENERATIONS.

haploid,

adj possessing just one set of nonhomologous chromosomes. Also called
monoploid or
monoploidic.

haploid
