haploid Biology1. (esp of gametes) having a single set of unpaired chromosomes 2. a haploid cell or organism haploid[′ha‚plȯid] (genetics) Having half of the diploid or full complement of chromosomes, that is, one complete set, as in mature gametes. haploid
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 (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.n. An organism having haploid cells.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 - (of a cell nucleus) containing one of each type of chromosome.
- 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.
