Meiosis is the process by which the nuclei of certain somatic cells reduce the number of chromosomes by half, in order to produce gametes, or sex cells. The production of gametes is known as gametogenesis. Gametes must have only half the normal number of chromosomes (a condition known as haploid) so that when two gametes (an egg and a sperm) combine, the resulting zygote (fertilized egg) will have the full number of chromosomes-a condition called diploid.

∙ 14y agoChromosome number is a constant that is characteristic of the species. Meiotic division halves the chromosome number, so that when the 2 gametes fuse together, the chromosome number is back to what it was in the previous generation. Improper gametogenesis can lead to polyploidy which is fatal is animals and humans, but usually produces viable offspring in plants (with increased crop yield in many cases).

Which is a correct statement about gametogenesis?
In gametogenesis, germinal cells multiply by mitosis and mature gametes are formed by meiosis
What role do germ cells play in gametogenesis?
They produce cells that divide by mitosis and then undergo meiosis to form gametes.
What form of cell division halves the number of chromosomes?
Meiosis. Takes place during gametogenesis, the formation of sperm or ova. The final sperm or ova formed will each contain 23 chromosomes, haploid number.
What is the process by which gametes are formed from diploid nuclei?
Meiosis creates four haploid cells, or gametes, from one diploid cell. Each gamete contains half of the chromosomes theorganismusually has. Gametogenesis creates mature gametes, being able to reproduce.
What are the sites of gametogenesis?
In plants it is in gametophytes. In animals it is in the gonads.
The term for the production of gametes by means of meiosis?
The term for the production of gametes by means of meiosis is gametogenesis. Meiosis reduces the number of chromosomes by half, making possible the combination of two gametes to form a new individual.
Which is a correct statement about gametogenesis?
In gametogenesis, germinal cells multiply by mitosis and mature gametes are formed by meiosis
What is the term for the production of gametes by means of meiosis?
Gametogenesis.
What process are gametes produced through?
The Nuclear process that Gametes are formed is called Gametogenesis.
What process occurs only in the information of gametes?
During the formation of gametes - a process called gametogenesis - meiosis is a process which only occurs during this period. Meiosis is a special type of cell division necessary for sexual reproduction.
What role do germ cells play in gametogenesis?
They produce cells that divide by mitosis and then undergo meiosis to form gametes.
Are cells that exit meiosis immediately capable of fertilization?
At the end of meiosis, haploid cells are produced. These cells need to further develop into mature gametes capable of fertilization, a process called gametogenesis.
During which type of gametogenesis would you see polar bodies?
oogenesisMeiosis I and Meiosis IIPolar Body are porduced in the process of Egg or ovum (female Side).
Is Interkinesis is the most important process that increases variety in human gametogenesis?
No, interkinesis has nothing to do with genetic variation. The two features of meiosis that increase genetic variation in gametogenesis are (a) crossing over during prophase I, and (b) the independent assortment of chromosomes during anaphase I and anaphase II.
Are there carrier forms of xxx syndrome?
no there r no carrier forms for triple x syndrome. this is just a nondisjunction during meiosis of gametogenesis. this can happen with either spermatogenesis or ovariogenesis
Why is gametogenesis essential to humans?
Gametogenesis is essential to humans who want to reproduce. Gametogenesis, however, is not an essential life function.
Sex cells divide using the process called?
The production of sex cells is called "gametogenesis." This makes sense since a gamete is a reproductive cell and "genesis" means creation or beginning. If the sex cells being produced are sperm the process is called "spermatogenesis" and if the sex cells being produced are eggs it is called "oogenisis."
