All human cells have 46 chromosomes, 23 pairs. In sexual reproduction, if an egg and a sperm each with 46 chromosomes joined then the zygote would have 92 chromosomes. To keep this from happening, cells undergo meiosis. In meiosis the cells replicate the chromosomes and divide then divide again so they end up with only 23 chromosomes. Cells with half the number of chromosomes are called gametes.
What else can I help you with?
For what reasons might a cell use mitosis?
To Heal Injuries by reproducing itself (Cell division).
What two cell division process use DNA replication?
The two cell division processes that use DNA replication are mitosis and meiosis. Mitosis is a type of cell division that results in two identical daughter cells that are genetically identical to the parent cell. Meiosis is a type of cell division that produces four daughter cells, each with half the number of chromosomes as the parent cell, and is involved in the production of gametes for sexual reproduction.
Cells produced by meiosis have only one of each chromosome What name do you use to describe this cell?
A Haploid cell.
Do jellyfish use mitosis or meiosis?
Jellyfish primarily use meiosis for reproduction. During meiosis, the jellyfish's cells divide to create sex cells that have half the number of chromosomes, allowing for genetic diversity in offspring. Mitosis, on the other hand, is the process of cell division for growth and repair.
Does meiosis use normal body cells to produce gametes?
No, meiosis does not use normal body cells to produce gametes. Meiosis is a specialized type of cell division that occurs in the reproductive organs to produce gametes (sperm and egg cells) with half the number of chromosomes as a normal body cell.
Why would a cell use meiosis?
to create an offspring with 23 chromosomes in other words to reproduce
What is cell division called in the gametes?
The type of cell division which leads to gametes is called meiosis. This results in four haploid daughter cells (cells with half the number of chromosomes as the original cell).Gametes themselves do not divide until after they have fused (during fertilization) and become a zygote. After this point they are no longer gametes - but the type of division that the zygote undergoes is mitosis.
What 2 cell division processes use DNA replication?
Mitosis and meiosis are the two cell division processes that utilize DNA replication. During both processes, DNA is replicated in the S phase of the cell cycle to ensure that each daughter cell receives an identical copy of the genetic material.
How do you use meiosis in a sentence?
Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of gametes (sperm and egg cells) used in sexual reproduction.
The growth repair the use of food in your body are what part of what cell process?
metabolism
What type of cell division do skin cells use to multiply?
Skin cells use mitosis to multiply. Only sex cells use meiosis to multiply.
Which cells use meiosis instead of mitosis?
All somatice ( that is body cells) use mitosis. Only gamates (sex cells) use meiosis to produce the egg cell that is produced by the females ovaries or the sperm cell that is produced by the male testies.
