Why do gametes need 12 the number of chromosomes of a regular body cell?

Gametes require half the number of chromosomes of a somatic (regular) cell as gametes are the sex cells. When gametes combine to make a zygote (a fertilised cell), the complete number of chromosomes will be present.

Why is it neccessry to reduce the chromosome number of gametes but not other cells of an organism?
Gametes are sperm and egg cells. When the sperm fertilizes the egg, their genetic material is joined to form a new cell called a zygote. Because both the sperm and egg cells have half the number of chromosomes as in normal body cells, the zygote will have the full number of chromosomes as in normal body cells.
In what type of cell division does the chromosome number reduce by one half and gametes form?
Meiosis produces gametes which have half the number of chromosomes that other cells of the body have.
How is the nucleus of the sperm cell different to the nucleus in the body cell?
a gamete nucleus has only half the number of chromosomes in it than a regular body cell. in humans a regular body cell has 46 chromosomes (23 pairs) in the nucleus, but a gamete ie sperm or egg cell has only 23 chromosomes, which are all unpaired. during fertilization the 23 chromosomes from a sperm and the 23 from the egg cell combine and pair up.
How many chromosomes are present in human haploid and diploid cells?
human diploid numbers are 46 chromosomes (the total amount of chromosomes) and the haploid number is 23 (half the number of chromosomes) in meiosis the desired number is the haploid number for gametes (sex cells) and it becomes the diploid number after fertilization and for mitosis its the diploid number because it wants to maintain its chromosomes since its not sexual reproduction
In a dogs body each cell has 78 chromosomes How many chromosomes are there in a dog's sperm cells?
There's no good reason for it; the number of chromosomes an animal has doesn't really have much to do with anything.
Gametes have what kind of Chromosomes?
Gametes have haploid chromosomes, which means they have half the number of chromosomes of other cells in the body.
How does the number of chromosome in a persons gametes compare with the numbers of chromosomes in the body cells?
There are half as many chromosomes in gametes than in normal body cells.
How many chromosomes in human gametes?
23, there are 23 chromosomes in human gametes
What cell has half number of chromosomes in body cells?
gametes
How does the number of chromosomes in gametes of an organism that reproduces sexually differ from the numbers of chromosomes in other cells?
Unlike somatic (body) cells, gametes have two time the number of chromosomes as body cells. Gametes (2n). Body cells (n). For example, human 46 chromosomes in gamete cells but half of that (23) in body cells.
An organisms gametes have double the number of chromosomes found in the organisms body cells.?
No, a gamete has half the number of chromosomes as compared to the organisms body cells.
Why must gamete have only half the number of chromosomes found in a body cell?
A gamete will only have one half of the number of chromosomes found in body cells because two gametes have to come together. This means that the two gametes have to have only half of the chromosomes.
Why must a gamete have only one half the number of chromosomes in body cells?
A gamete will only have one half of the number of chromosomes found in body cells because two gametes have to come together. This means that the two gametes have to have only half of the chromosomes.
Why is this important each of the haploid sex cells has only half the number of chromosomes as the original diploi d cell?
Gametes (or sex cells) are haploid in nature. This means they have half the number of chromosomes present in a regular body cell (or somatic cell). The male and female gametes unite in a process called fertilization to give rise to the offspring. Since both the male and female gametes have haploid number of chromosomes, the final offspring will end up having the diploid number of chromosomes.
How does the number of chromosomes in a grasshoppers body cell compare to the number in its sex cell?
sex cells(gametes) are haploid in nature as compared to body cells(somatic cells) thus the number of chromosomes in a sex cell of a grasshopper is half the number of chromosomes in a body cell
Is the number of gametes twice the number of chromosomes found in the body cells?
Gametes are cells, in humans they contain 23 chromosomes. Body Cells (Properly Called: Somatic Cells) in humans contain 46 chromosomes (2 sets of 23). Some differences or problems can cause this number to change in specific humans, gametes, and somatic cells. Muscle cells may have hundreds of chromosomes, red blood cells have none.
How do the number of chromosomes compare in gametes and somatic cells?
I will assume that you mean human cells. Somatic cells are diploid (2n), containing two sets of chromosomes, one of paternal, one of maternal origin. Gametes, on the other hand, are haploid (n), with a single set of chromosomes, ie. half as many as the somatic cell. Now, the haploid chromosome number (n) is characteristic of the species, and in humans this number happens to be 23. Therefore a human gamete has 23 chromosomes, and a human somatic cell 23 pairs, or 46 chromosomes.
