Both haploid and diploid cells can undergo mitosis. When a haploid cell undergoes mitosis, it produces two genetically identical haploid daughter cells; when a diploid cell undergoes mitosis, it produces two genetically identical diploid daughter cells.
Does all gametes undergo mitosis?
Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes.
Do haploid gametes undergo meiosis?
Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg). The development of a new progeny organism is then initiated by the fusion of these gametes at fertilization.
Is mitosis ever haploid?
After mitosis two identical cells are created with the same original number of chromosomes, 46. Haploid cells that are generated through meiosis, such as egg and sperm, only have 23 chromosomes, because, remember, meiosis is a “reduction division.”

What will happen if gametes undergo mitosis?
Gametes are made via meiosis which produces cells with n=23 instead of diploid cells. If gametes were produced instead by mitosis each gamete would be diploid not haploid. During fertilization of diploid gametes, the zygote would become 4n=92. With each new generation the number of chromosomes would double.
Why can’t gametes undergo mitosis?
When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. … Unlike in mitosis, the gametes produced by meiosis are not clones of the original cell, because each gamete has exactly half as many chromosomes as the original cell.
Why are animals gametes haploid?
Animals are diploid organisms (2n) and undergo sexual reproduction. This sexual reproduction causes them to produce gametes via a process called MEIOSIS. … This means that meiotic division produces haploid gametes (n) from a diploid animal.
Do sperm cells undergo meiosis?
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. … Meiosis begins following one round of DNA replication in cells in the male or female sex organs.
Where does mitosis occur in the body?
Cell division by mitosis occurs in all human body cells except the gonads (sex cells). During mitosis, the DNA is exactly copied and a new daughter cell created with the same number of chromosomes as the parent cell, ie 46.
