A haploid germ cell has the same number of chromosome sets as a gamete, which is half the number of chromosome sets found in a somatic cell. This enables the gametes to fuse during fertilization to restore the diploid number of chromosomes in the zygote.
An inactivated X chromosome would be found in the nucleus of a female somatic cell.
If you mean haploid, as in half of each chromosome, or containing only one chromatid from each full chromosome, thenthe cell is called haploid.
Human somatic (body) cells contain two sets of 23 chromosomes. Human gametes (sperm and egg cells) contain one set of 23 chromomes -- 22 autosomes and 1 sex chromosome. Only a sperm cell can carry a y chromosome. A sperm cell can also carry an x chromosome. The ovum can carry only an x chromosome, never a y chromosome. So a cell containing 22 autosomes and a y chromosome must be a sperm cell.

They have half the number of the somatic (parent) cell. So if a parent cell had 46 chromosomes in its nucleus, then its gamete would have 23(one chromosome from each pair).
A haploid germ cell has the same number of chromosome sets as a gamete, which is half the number of chromosome sets found in a somatic cell. This enables the gametes to fuse during fertilization to restore the diploid number of chromosomes in the zygote.
The diploid number of chromosomes in a horse's cell is 64, therefore they have 32 pairs of chromosomes in their somatic cells.
An inactivated X chromosome would be found in the nucleus of a female somatic cell.
23 Pairs
The number of chromosomes in a mature somatic cell depends on the species, but it is the diploid number (2X). In a human somatic cell, that number is 46.
If you mean haploid, as in half of each chromosome, or containing only one chromatid from each full chromosome, thenthe cell is called haploid.
The term for a somatic diploid nucleus is "2n" where "n" represents the number of unique chromosomes in the cell. This means that the cell has two sets of chromosomes, one inherited from each parent, and is the typical chromosome number for most human cells.
Human somatic (body) cells contain two sets of 23 chromosomes. Human gametes (sperm and egg cells) contain one set of 23 chromomes -- 22 autosomes and 1 sex chromosome. Only a sperm cell can carry a y chromosome. A sperm cell can also carry an x chromosome. The ovum can carry only an x chromosome, never a y chromosome. So a cell containing 22 autosomes and a y chromosome must be a sperm cell.
A chimpanzee with 48 chromosomes will have 24 dyads in a somatic cell during metaphase. In metaphase, each chromosome consists of two sister chromatids, which are referred to as dyads.
Yes, In most cases all somatic cells are diploid but in some organisms it is not the case, Gametophytes of plants are always haploid. Bacteria are also haploid. In angiosperms, the endosperm; which is considered somatic; is a tissue consisting triploid cell. Some time its chromosome number varies from 2n to 15n.In some conifers , like Sequoia sempervirens, chromosome number is 6n (Hexaploids).So, even in somatic cells, there is a large variety in chromosome number.
