With one set of chromosomes.
An organism with one basic chromosome set, symbolized by n; the normal condition of gametes in diploids.
A cell with one set of chromosomes; half as many chromosomes as the normal somatic body cells contain. A characteristic of sex cells.
The reduced, or n, chromosome number, characteristic of the gametophyte generation.
Referring to a cell such as a gamete where each chromosome occurs only once. In humans the haploid number of chromosomes is 23.
To a cell, specifically a gamete, or mature sex cell, that has half the chromosome number characteristic of the species. Thus, in humans, the sex cells—the ovum (egg) and spermatozoon—each have the haploid chromosome number 23; at fertilization, when the gametes fuse to form a zygote, the zygote has the chromosome number 46, characteristic for humans.
Describing cells, nuclei, or organisms with a single set of unpaired chromosomes. In man the gametes are haploid following meiosis. Compare diploid, triploid.
An adjective describing organisms, cells or nuclei that have a single set of unpaired chromosomes. Human beings have haploid gametes following meiosis.
Possessing half the diploid or normal number of chromosomes found in somatic or body cells. Such is the case of the germ cells — ova or sperm — following the reduction divisions in gametogenesis, the haploid number being 23 in humans.
