Meiosis gamete formation

WebFormation of the actual gamete nuclei can now proceed simply through a second cell division, division II of meiosis, without further DNA replication. The duplicated chromosomes align on a second spindle, and the sister chromatids separate to produce cells with a … WebA gamete is the male or female reproductive cell that contains half the genetic material of the organism. When two human gametes meet i.e. a sperm cell and an ovum then a zygote formation takes place which is also known as a fertilized egg. Gametes are produced by the cell division which is called meiosis.
