What halves the number of chromosomes and results in gametes or spores?
StormTaylor
Meiosis is a type of division which results in gametes. This occurs in order for sexual reproduction to proceed.

How many chromosomes in human gametes?
23, there are 23 chromosomes in human gametes
What happens if the gametes aren't haploid?
The whole purpose of reducing the gamete to contain half the number of normal chromosomes is so that normal chromosome numbers can be achieved again when the gametes fuse to form a zygote. If the gamete is not halved, polyploidy results. This is a generic term to describe having more than the normal number of chromosomes.
What cell has haploid number of chromosomes?
Gametes.
Do gametes have a even or odd number of chromosomes?
Even
If a cell with 40 chromosomes undergoes mitosis each of the daughter cells will have chromosomes.?
Meiosis results in gametes that have half the number of chromosomes of other cells. A gamete carries one of each pair of homologous chromosomes. Their are 46 chromosoes in Meiosis I and 23 in Meiosis II.
Does meiosis increaase the number of chromosomes in a cell?
No, it halves it. This is because Meiosis is only used in the production of sex cells (gametes), and two gametes are needed for a zygote to be created, and each carries half the normal number of chromosomes. When they join together during fertilization their offspring will carry the normal number of chromosomes.
If a diploid organism has a genome consisting of twenty two chromosomes its gametes will have how many chromosomes?
Gametes have half the number of chromosomes - therefore if the diploid number is 22, the gametes would have 11 chromosomes.
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.
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.

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.
What cell has haploid number of chromosomes?
Gametes.
All cells within an organism will have the same number of chromosomes except the gamete?
All cells within an organism will have the same number of chromosomes, which is the diploid number. The gametes, on the other hand, will have the haploid number of chromosomes.
If somatic cell has 30 chromosomes how many are in the gametes?
Since gametes are haploids, they would each contain haploid number of chromosomes, 15 chromosomes.
What is the process called that guarantees that the number of chromosomes in gametes is half the number of chromosomes in body cells is?
Since gametes divide by a special process, meiosis, they will always have half the number of chromosomes as regular body cells. This is because the chromosomes only copy themselves once, however they are split apart twice. Think of it as a math problem. If the original cell count is, for example, 2 chromosomes, and each chromosome makes a copy of itself, the cell will have 4 chromosomes. During meiosis 1, the cell divides, and the chromosomes split, resulting in each daughter cell having 2 chromosomes, the same as the original. However, in meiosis 2, they divide again without making another copy of themselves, so that by the time meiosis is done, each one of the 4 cells that results have 1 chromosome, half the number of the original cell. 2x2=4 4/2=2 2/2=1
Do gametes have a even or odd number of chromosomes?
Even
