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 fertilization restores the diploid number of chromosome in an orgaism with a haploid chromosome of 8 how many chromosomes are present in the spermatogonium?

Fertilization restores the diploid number by combining one haploid gamete from the mother with one haploid gamete from the father to form a zygote with the full diploid set of chromosomes. In an organism with a haploid chromosome number of 8, each spermatogonium would have 16 chromosomes because they are diploid cells that undergo mitosis to produce sperm cells with the haploid number.


What process union of egg and sperm restores chromosome number?

The union of an egg and sperm restores the chromosome number through the process of fertilization. During fertilization, the haploid egg and haploid sperm fuse to form a diploid zygote, which contains the full complement of chromosomes (46 in humans). This restores the normal chromosome number in the resulting offspring.


How many sperm cells are produced in males when one diploid cell enters gametogenesis?

One diploid cell entering gametogenesis will undergo meiosis and produce four haploid cells, each of which will develop into a sperm cell. Therefore, one diploid cell entering gametogenesis will result in the production of four sperm cells.


What is the diploid chromosome number in humans?

The diploid chromosome number in humans is 46.


A diploid cell missing a chromosome is called a?

The condition in which a diploid cell is missing a chromosome or has an extra chromosome is called aneuploidy.


Does a zygote ha ve a diploid chromosome number?

yes zygote do have diploid chromosome number


What is it when a diploid has an extra chromosome?

no


What is trisomics?

A diploid cell with an extra chromosome. Basically a diploid with an extra chromosome of one type, producing a chromosome number of the form 2n + l.


Are diploids split into half?

The diploid cells split into haploid cells only during gametogenesis.


Why meiosis and gametogenesis are always interlinked?

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.


What is gametogenesis called in males?

Gametogenesis in males is called spermatogenesis. During this process, diploid cells called spermatogonia undergo mitosis and differentiation to form haploid sperm cells.
