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.
Fertilization involved the fusion of the male and female gametes. Gametes are sex cells that contain haploid number of chromosomes. The haploid number is one full chromosomal set of an organism and is denoted by the letter n. The male gamete contains n number of chromosomes. The female gamete also contains n number of chromosomes. When the two gametes combine, 2n number of chromosomes result, thus restoring the diploid number.
Fertilization (from Sylvia Mader's "Inquiry into Life", twelfth edition, Chapter 5 "Mitosis and Meiosis", pag74)
At fertilization the diploid number is restored when the egg and sperm unite.
The diploid number of chromosomes is re-established through fertilization. Fertilization initiates the development of a new diploid organism containing genetic information from both parents.
The answer is actually fermentation.
Fertilization.

Fertilization restores diploid cells.
A cellwith two of each kind of chromosomeis called a diploid cell and is said to contain a diploid, or 2n, number of chromosomes.
Diploid
yes, the gametophyte generation of a moss is haploid. While the sporophyte generation of a moss is diploid.
housfly has 12 chromosomese in diploid
it multiplies itself
Four sperm cells are produced in males when one diploid cell enters gametogenesis.
Fertilization restores diploid cells.
The condition in which a diploid cell is missing a chromosome or has an extra chromosome is called aneuploidy.
yes zygote do have diploid chromosome number
no
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.
The diploid cells split into haploid cells only during gametogenesis.
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.
it has split in two
