haploid cell
(hap-loyd) [Gk. haploos, single + ploion, vessel]
A cell containing only one set of chromosomes (n).
Hardy-Weinberg equilibrium ...
Haploid cell. A cell containing only one set, or half the usual (diploid) number, of chromosomes.
Haploid cells can live indefinitely in the haploid condition. However, if two cells of opposite mating types meet, they can fuse and enter the diploid phase of the cell cycle.
This is not as rare event as you might expect.
Haploid cells have one complete set of chromosomes. In animals, gametes (sperm and eggs) are haploid.
Homologous Chromosomes ...
Haploid cells possess only one set of a chromosome. For example, a diploid human cell possesses 46 chromosomes and a gamete created by a human is haploid possesses 23 chromosomes.
haploid cell a cell containing only one of each type of chromosome characteristic of its species
haptens Molecules of small molecular weight (usually) that are immunogenic only when attached to carrier molecules, usually proteins.
The four haploid cells formed at the end of meiosis. The term was formerly used for the four chromatids making up a chromosome-pair at the first division of meiosis.

Alternatively, a haploid cell with two chromatids per chromosome also has 46 chromatids. However, this doesn't occur naturally in humans.

megaspores Four haploid cells produced by meiosis in the ovule of a þower. Usually, three of these cells degenerate, with the remaining cell becoming the female gametophyte phase of the plant's life cycle.
See Haploid cell. Directional cloning. DNA insert and vector molecules are digested with two different restriction enzymes to create noncomplementary sticky ends at either end of each restriction fragment.
Gamete -- an haploid cell.gel electrophoresis the process by which nucleic acids (DNA or RNA) or proteins are separated by size according to movement of the charged molecules in an electrical field.
We [began to work] with yeast cells because they were susceptible to genetics; because they would grow as haploid cells. We couldn't do the same kind of genetics with human cells. We were looking for the things in common between yeast and human cells.
They are produced from pollen or egg cells used to produce a haploid cell line and the haploid cells undergo chromosome doubling. Haploid cells occur naturally in the gametophytic phases of higher plants in their ovules and pollen.
A haploid cell only has one set of chromosomes, and most of the time that refers to the so-called sex cells, either eggs or sperm.
Meiosis produces 4 haploid cells. Mitosis produces 2 diploid cells. The old name for meiosis was reduction/ division.
In meiosis, a diploid cell divides to produce four haploid cells, each with half the original chromosome content. For this reason, meiosis is often called a "reduction division".
Cells with only one set (23 in a human) are called haploid cells. Haploids are most often found in cells involved in sexual reproduction such as a sperm or an egg. Haploid cells are created in cell division termed meiosis.
in Dictyostelium discoideum, the solitary haploid cell of the vegetative life cycle that lives on bacteria and reproduces by binary fission until the food supply is exhausted.

A small haploid cell, produced during oogenesis in female animals, that does not develop into a functional ovum. A similar situation arises in the development of the egg cell of higher plants, in which only one fertile gamete is produced from meiosis.
[Gr. spermatos - seed, semen]. Haploid cell in male testes, formed from spermatocyte by meiosis and will differentiate into a spermatozoon.
spermatid [Gr. spermatos - seed, semen]. Haploid cell in male testes, formed from spermatocyte by meiosis and will differentiate into a spermatozoon.

Meiosis
The process of nuclear division associated with the formation of gametes or of haploid cells from a diploid.
In instances of sexual reproduction, the cellular process of meiosis is first necessary so that haploid daughter cells, or gametes, can be produced. Two haploid cells then fuse to form a diploid zygote, ...
