gamete

 [gam´ēt]
1. one of two haploid reproductive cells, male (spermatozoon) and female (oocyte), whose union is necessary in sexual reproduction to initiate the development of a new individual.
2. the malarial parasite in its sexual form in a mosquito's stomach, either male (microgamete) or female (macrogamete); the latter is fertilized by the former to develop into an ookinete. adj., adj gamet´ic.

gam·ete

(gam'ēt),
1. One of two haploid cells that can undergo karyogamy.
2. Any germ cell, whether oocyte or sperm.
[G. gametēs, husband; gametē, wife]

gamete

(găm′ēt′, gə-mēt′)
n.
A reproductive cell having the haploid number of chromosomes, especially a mature sperm or egg capable of fusing with a gamete of the opposite sex to produce a zygote.

ga·met′ic (-mĕt′ĭk) adj.
ga·met′i·cal·ly adv.

gamete

Genetics A mature ♀ or ♂ reproductive cell–sperm or ovum/egg with a haploid set of chromosomes–23 for humans. See Chromosome, Haploid, Macrogamete, Microgamete, Nullisomic gamete.

gam·ete

(gam'ēt)
1. One of two haploid cells undergoing karyogamy.
2. Any germ cell, whether oocyte or sperm.
[G. gametēs, husband; gametē, wife]

gamete

A cell, such as a sperm or ovum, possessing half the normal number of chromosomes (haploid) and capable of fusing with another gamete in the process of fertilization, so that the full (diploid) number of chromosomes is made up. From the Greek gamos , marriage.

gamete

or

germ cell

a specialized HAPLOID cell that fuses with a gamete from the opposite sex (or mating type) to form a diploid ZYGOTE. In simple organisms, the process is called isogamy (see ISOGAMETE), and OOGAMY in more complex organisms. In animals where oogamy occurs male gametes are called sperm, the female gametes eggs. The situation in higher plants is more complicated, but essentially the male gamete is the generative nucleus found in the POLLEN GRAIN while the female gamete is the egg cell found within the EMBRYO SAC.

Gamete

An egg (ovum) from the female or a mature sperm from the male.

While Parry does not interrogate the role race plays in the global sperm market, it is revealing to question how sex cells become qualified in racial terms to show how race is rather the outcome than the basis of laboratory practices:
Sex cells recorded in the other months showed similar diameters, indicating that there is a proliferation of new elements or cells in early maturation stages throughout the period.
Fertilize--the joining of a female sex cell and male sex cell to produce a new organism
As it extends, the tube transports its passengers, the male sex cells, down through the style, delivering them to the female cells--where fertilization occurs.
This is the means by which a human being produces haploid (containing only 23 chromosomes) sex cells, or gametes.
To produce fertile offspring, scientists think chromosomes (cell structures that house all the genes) from both a mother and father may need to pair off evenly during meiosis, a process of cell division that produces sex cells. For the hardy mule, for example, this is impossible, since its father--a donkey--has 62 chromosomes and its mother--a horse--has 64.
Sex cells, the sperm and the egg, have only one set of 23 chromosomes apiece.
The union of two such sex cells (male germ cell and female germ cell) to form a zygote constitutes the process of fertilization and initiates the life of a new individual." [Emphasis mine.] [Bradley M.
(It is now known that there are forty-six chromosomes in human cells.) Furthermore, he discovered that in the formation of the sex cells (that is, the ova and spermatozoa), the division of chromosomes during one of the cell divisions was not preceded by a doubling.
However, scientists are still not sure why age would reduce the condition of a man's sperm, seeing as he makes a new and continuous supply of the sex cells throughout his life.
Nicotine was affecting both the lung cells and the sex cells in ways that caused the lungs that developed from those cells to develop abnormally, causing asthma.
Evening the odds Female flower parts may be able to influence their mix of suitors by delaying the starting gun that sends pollen racing toward female sex cells. Without this delay, the first pollen grains to land may sire most of the seeds.
