The diploid number in grasshoppers is 24, so the haploid number ( sex cell number ) would be 12. So, the comparison would be 1/2 the number in sex cells.

Describe what happens to the number of chromosomes when two grasshopper sex cells join to fertilization?
2n. Given that the sperm has (n) number of chromosomes, and the egg has (n) number of chromosomes, then the zygote will contain (2n) number of chromosomes. For example, a sperm cell of a human contains 23 chromosomes. The egg cell also contains 23 chromosomes. After they join, the resulting zygote will contain 46 chromosomes.
After gametogenesis takes place which process restores the diploid chromosome number of the species for the next generation?
In the S phase before mitosis, the chromosomes duplicate into sister chromatids before spearating during mitosis. The number of chromosomes remainds diploid because they double before they are halved.
How does meiosis maintain a constant number of chromosomes in the body cells of organisms that reproduce sexually?
The purpose of meiosis is to divide the number of chromosomes in gamete cells (spermatazoa and oocytes) to the haploid number (23 chromosomes). Meiosis ensures the proper number of chromosomes to form a zygote, which is 46 chromosomes (diploid number), during fertilization. Essentially, somatic cells (all other cells except gamete cells) require 46 chromosomes. 23 of these come from the mother and the other 23 from the father. During fertilization, the sperm and oocyte containing the haploid number come together to produce the diploid number. Thus, without mieosis, sexual reproduction would result in zygotes with twice the number of chromosomes (and would continue exponentially)... something that would cause deformities and/or death of the future fetus.
Why cant mitosis provide for the sexual reproduction of offspring that contain the same number of chromosomes as the parents?
Meiosis works to produce gametes, not mitosis.
Why does the number of chromosomes in the sperm and egg have to be half the number of chromosomes in the other cells of an organism?
I have the same queston
What happens to the number of chromosomes when 2 grasshopper sex cells join in fertilization?
The number of chromosomes doubles in comparison to the sex cells.
What did sutton study?
He studied grasshoppers, well the number of chromosomes in a grasshopper. grasshoppers contain about 24 chromosomes.

Walter Sutton discovered that sex cells of grasshoppers have?
He discovered that grasshoppers only have half the number of chromosomes in the body cells.
When during the human cycle is the diploid number of chromosomes restored?
Fertilization
Do grasshoppers sex cells have half the number of chromosomes as body cells?
Yes.
Why does a sex cell not receive both chromosomes from a pair normally in grasshoppers?
Because in the events of Meiosis the chromosomes split and then the sex cell only has half the number of chromosomes. Once the sperm & egg unite (fertilization) then the chromosomes pair up, and you get all 46 chromosomes.
What sequence shows chromosomes number during fertilization?
hapliod is 23 and diploid is 46

In the S phase before mitosis, the chromosomes duplicate into sister chromatids before spearating during mitosis. The number of chromosomes remainds diploid because they double before they are halved.
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
Can the number of chromosomes in a reproductive cell be greater than the number chromosomes in an organism's body cell?
No. The reproductive cells (eggs, sperm, ova and pollen) all contain half the number of chromosomes of an organisms body cell. This means that at fertilization the two reproductive cells (or gametes) combine to form a single cell with the appropriate number of chromosomes.If a gamete had more chromosomes than a normal cell then fertilization would lead to even more chromosomes and an offspring that would be seriously genetically compromised.
What did Sutton observe about the relative numbers of chromosomes in the body cells and sex cells of grasshoppers?
body cells of a grasshopper has 24 chromosomes and 12 chromosomes in the sex cells so as many body cell chromosomes you have you will have half that number of chromosomes in your sex cells.
