Human cells contain 23 pairs of chromosomes for a total of 46.
Female cells contain the sex chromosomes XX. A female gamete (ovum/egg) contains one X chromosome.
No. The reproductive cells (eggs, sperm, ova and pollen) all contain half the number of chromosomes of an organisms body cell. This means that at fertilization the two reproductive cells (or gametes) combine to form a single cell with the appropriate number of chromosomes.If a gamete had more chromosomes than a normal cell then fertilization would lead to even more chromosomes and an offspring that would be seriously genetically compromised.
Gametes are reproductive cells produced by a type of cell division called meiosis. They contain only one set of chromosomes and are said to be haploid.
Chromosomes are not reproductive cells. They are structures within cells that carry genetic information in the form of DNA. Reproductive cells, like eggs and sperm, contain half the number of chromosomes as other cells in the body.
Reproductive cells have half the number of chromosomes as body cells, so if a body cell has 22 chromosomes, then the reproductive cells (sperm or egg) would have 11 chromosomes. This is because during sexual reproduction, the sperm and egg combine to form a new cell with the full number of chromosomes.
As you may know, almost all our cells contain pairs of chromosomes - 23 pairs to be exact. These are called diploid. Haploid cells contain only one chromosome from each pair. Reproductive cells (both male and female) are haploid, so they can fuse and form a diploid cell with chromosomes from both the male and the female. The female reproductive cell (which is haploid) is the ovum, or egg cell.
Female cells contain the sex chromosomes XX. A female gamete (ovum/egg) contains one X chromosome.

A female reproductive cell is called an ovum
eggThe cells formed in the female reproductive organs which contain stored food along with the other cell parts are called eggs.
In humans a male reproductive cell is the sperm, while the female reproductive cell is the egg.

Chromosomes are not reproductive cells. They are structures within cells that carry genetic information in the form of DNA. Reproductive cells, like eggs and sperm, contain half the number of chromosomes as other cells in the body.
A frog somatic cell typically has a diploid number of chromosomes, which is twice the haploid number. This means it has two sets of chromosomes. On the other hand, a frog egg cell is haploid, meaning it only has one set of chromosomes. In frogs, both the somatic cell (2n) and the egg cell (n) have 26 chromosomes.
A primary spermatocyte with 46 chromosomes will undergo meiosis and yield four spermatids with 23 chromosomes. A primary spermatocyte undergoes meiosis I two haploid secondary spermatocytes are produced.

How many chromosomes does each new cell contain after mitosis if the original cell had 52 original cell chromosomes?
