how many chromosomes are present in a single spermatogonium?
480908
It is a haploid cell, meaning it has only one copy of each allele (one of each chromosome instead of two). Normal diploid cells have two copies of each chromosome, for a total of 46. Spermatids have half this number, for a total of 23 chromosomes.

In human somatic cells, there are 23 pair (2n) of chromosomes, and there are 23 pairs in all cells except in gametes. Of the 23 pair in somatic cell, 22 pair are autosomes, while two are sex chromosomes.

For example, in humans, somatic cells contain 46 chromosomes organized into 23 pairs. By contrast, gametes of diploid organisms contain only half as many chromosomes. In humans, this is 23 unpaired chromosomes.

Explanation: Haploid means half of the normal. A normal human cell has 46 chromosomes or 23 pairs of chromosomes. So a sex or germ cell has 23 chromosomes none of them paired.

Expert Answer The human body consists of millions of cells; each cell (liver, intestinal etc) contains 23 pairs of chromosomes except for germ cells (egg and sperm) and red blood cells. Thus a total of 46 chromosomes are present in human cells.

Answer and Explanation: Sperm cells have 23 chromosomes.

How many chromosomes are found in the sperm cell? The diploid chromosome number for a rabbit is 44.

Human diploid cells have 46 chromosomes (the somatic number, 2n) and human haploid gametes (egg and sperm) have 23 chromosomes (n). Retroviruses that contain two copies of their RNA genome in each viral particle are also said to be diploid.

The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.

(The gametes of diploid organisms contain only single unpaired chromosomes and are called haploid.) Each pair of chromosomes comprises one chromosome inherited from the father and one inherited from the mother. For example, in humans, somatic cells contain 46 chromosomes organized into 23 pairs.

Because they have only half the total chromosomes in a somatic cell, they are termed haploid (n). In a human egg or sperm, there are 23 chromosomes, one of which is an X or Y.

In case of humans , there are 46 chromosome (2n) in each somatic cell .. during fertilization, two types of haploid ( n = 23 chromosome ) gametes ( sperm and ovum) fuse together to form a zygote(46 chromosomes) inside the female's body , that further develops produce an embryo.

In a human egg or sperm, there are 23 chromosomes, one of which is an X or Y. A human egg is haploid (has 23 chromosomes) and a sperm is haploid (has 23 chromosomes). Upon fertilization, the new baby now has the 'correct' human number of 46 chromosomes in each of its somatic cells.

Each pair of chromosomes comprises one chromosome inherited from the father and one inherited from the mother. For example, in humans, somatic cells contain 46 chromosomes organized into 23 pairs. By contrast, gametes of diploid organisms contain only half as many chromosomes.

The sperm cell, i.e., the male gametes of the fly would contain 6 chromosomes as the reproductive cell or sex cell which contain half the total no. of chromosomes in a species.

By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell.
347673
As gametes are formed, the 46 chromosomes from each parent cell (23 pairs of chromosomes) are divided through meiosis so that each gamete is haploid, having only 23 unpaired chromosomes.
