Chromosome numbers in gametes are always half that of normal cell. For example human cells have 46 chromosomes but a human gamete (sex cell e.g sperm/eggs) will have half that number which in this case will be 23. The number is chromosomes is halfed in gametes so that when the sperm meets the egg and the fuse to make a zygote that you get half the genetic material from your Mother and half from you Father, meaning you are not a clone.

∙ 13y agoIt's not, that would be very bad! They need to have a haploid number (ie. half the normal number) of chromosomes. This is so that when two gametes fuse, their two half-sets of chromosomes combine into a full set.

∙ 11y agoIt depends on what species are you referring to. Yes, the number of chromosomes in different species differ. For instance, in humans there are 46 chromosomes, two pairs of 23 chromosomes provided by the male and the female gametes.
The number of chromosomes in a gamete, depends on the species you're referring to.
But, if in a species gametes don't have equal numbers, that would result in an unhealthy offspring.

∙ 10y agoOrganisms or cells may be haploid (meaning they have 1 gene coding for every trait) or diploid (meaning they have a pair of genes coding for every trait), but chromosomes can't.
The reason why gametes are haploid is that during fertilisation genes from haploid sperm and genes from haploid egg mix forming a zygote, which have a pair of genes coding for every trait. If gametes were diploid they would form a tetraploid (I think I just made that term up) cell, which would die quite quickly.

How does the significance of meiosis maintained the chromosome number?
No. Meiosis results in halving of chromosome number. Chromosome number after one round of meiosis is half that of original chromosome number. Generally, meiosis takes place during gamete formation. So when two gametes fuse, they lead to restoration of the chromosome number. Hence chromosome number can be maintained in sexually reproducing organisms.
What To maintain the chromosome number of an organism the gametes must?
Be produced by meosis.
A human zygote is normally produced from two gametes that are identical in?
chromosome number
What chromosome is the sex determining chromosome?
That would be the chromosome number 23. Regarding the [sex] chromosome number 23, the female gametes always have a [haploid] X chromatid, whereas the male gametes are just as likely to possess a [haploid] X chromatid as they are to possess a [haploid] Y chromatid.
What would happen to the possible variation in the gametes if the number of chromosome pairs increased from two to three?

What effect does nondisjunction have on the chromosome number of the gametes?
It gives one of the gametes an extra chromosome and leaves the other gamete with one less chromosome.
Name the 2 human gametes and tell their chromosome number?
The human gametes are Male gametes are sperm and female gametes are eggs. And the gametes chromosome numbers are 42.
What To maintain the chromosome number of an organism the gametes must?
Be produced by meosis.
A human zygote is normally produced from two gametes that are identical in?
chromosome number
What best describes the function of meiosis?
reduces chromosome number by half, produces gametes
Does sperm contain x and y chromosome?
In humans the male sperm contains EITHER an X chromosome, or a Y chromosome since human gametes are haploid (n) in chromosome number.
What chromosome is the sex determining chromosome?
That would be the chromosome number 23. Regarding the [sex] chromosome number 23, the female gametes always have a [haploid] X chromatid, whereas the male gametes are just as likely to possess a [haploid] X chromatid as they are to possess a [haploid] Y chromatid.
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.
What does a gamete have?
Gametes normally contain only one set of chromosome – this number is called Haploid.
How mice gametes contain 20 chromosomes. How many chromosome do normal mice zygotes contain?
Since the gametes contain one half the number, the zygote will have to have the full number of 40.
What would happen to the possible variation in the gametes if the number of chromosome pairs increased from two to three?
