(1) A reproductive cell or sex cell that contains the haploid set of chromosomes, e.g. spermatozoon or sperm cell (male reproductive cell) and egg cell or ovum (female reproductive cell).

gamete -- Reproductive cells which fuse to form a zygote. Gametes are haploid, and may be differentiated into egg and sperm.
gamete
(gam-eet) [Gk. wife]
A haploid egg or sperm cell; gametes unite during sexual reproduction to produce a diploid zygote.

Gametes
Because pairs of chromosomes separate during meiosis I, gametes are haploid, that is, they carry only one copy of each chromosome. An Aa individual therefore produces two kinds of gametes: A and a.
gametes - reproductive cells; sperm and egg cells in animals.
gene - section of a chromosome which codes for a protein or RNA product.

Gamete A sperm or an ovum.
Gene In Mendelian terms - a unit of inheritance. In molecular terms - a region of DNA which contains the information to create either a functional RNA or a polypeptide chain.

Gamete (1N): NUCLEAR ENVELOPES form and chromosomes disperse as CHROMATIN. Meiosis has produced 4 DAUGHTER CELLS, each with 1N chromosomes and 1N DNA. Later, in fertilization, male and female 1N gametes will fuse to form a 2N ZYGOTE.
Two gametes fuse to create a new sporophyte. This cycle is known as alternation of generations, but a better term is "biological life cycle", as there may be more than one phase and so it cannot be a direct alternation.

The purpose of meiosis is to produce haploid (1n) gametes. Another purpose is to recombine genes from the parents of the individual in whom meiosis is occurring.
In vitro fertilization may take place with gametes from individuals other than the woman in whom the embryo may be implanted, or the male who is the prospective father. Whose authorization is necessary for collecting and analyzing DNA from the embryo?
They produce pollen, which contains the male gametes (sperm). The female parts of the flower are the stigma, style, and ovary. The egg (female gamete) is produced in the ovary.
In a finite population (as all biological populations are) the gametes contributing to the next generation are a sample of the alleles in the gene pool.
This means that when somatic cells are produced from two gametes, one allele comes from the mother, one from the father. These alleles may be the same (true-breeding organisms, e.g. ww and rr in Fig. 3), or different (hybrids, e.g. wr in Fig. 3).
Two successive nuclear divisions (with corresponding cell divisions) that produce haploid gametes (in animals) or haploid sexual spores (in plants and fungi) having one-half of the genetic material of the original cell.
Human diploid cells (those that are not gametes) characteristically exhibit 46 chromosomes, but this number can be as low as 2, as is the case for some ants and roundworms, or more than a thousand, ...
The haploid stage of a plant life cycle that produces gametes (by mitosis). It alternates with a diploid sporophyte generation.
When it's all over, you are left with four haploid cells that are called gametes. The eventual purpose of the gametes will be to find other gametes with which they can combine. When they do, they will form a new organism.
Epidemic spawning. Simultaneous shedding of gametes by a large number of individuals
Epipelagic zone. The 0- to 150-m-depth zone, seaward of the shelf-slope break

Fertilization: The joining or fusion of the male gamete (sperm) and the female gamete (egg) to form a zygote during sexual reproduction. See also gamete, zygote.
The second gene copy is silenced during gamete formation in the egg (when maternal gene copies are silenced) or the sperm (when paternal gene copies are silenced). This is known as genetic imprinting.
- Mode of asexual production in which there is no fusion of gametes but the structure involved are commonly concerned in sexual reproduction.
Arabidopsis ...
[Gr. pro- - a prefix meaning before, in front of; L. nux - nut]. The haploid, or reduced, nucleus of a gamete (ie. sperm and egg). The reduced nuclei of the sperm and egg join together in the fertilized ovum to form the zygote.
So there has to be a way to take those paired chromosomes and break them apart in order to make gametes; sperm and eggs. That's what meiosis is all about.
Gene flow: The exchange of genetic traits between populations by movement of individuals, gametes, or spores. It involves the spread of new variants among different populations through dispersal.
Fertilization: Fusion of female and male haploid gametes to form a diploid zygote from which a new individual develops.
Fetus: Final development stage before birth (following embryo).
Meiosis
The process of nuclear division associated with the formation of gametes or of haploid cells from a diploid.
pollen - in plants, the male germ cells produced in the anther. When ripe, pollen sacs at the end of the anthers split open to release the pollen. Each ripe pollen grain contains two male nuclei equivalent to male gametes. (Glossary of PM) ...
