If there are 13 pairs of homologous chromosomes in a primary spermatocyte how many chromosomes are there in a sperm?
There are 13 pairs of homologous chromosomes in a primary spermatocyte, which means there are 26 chromosomes. During meiosis, the primary spermatocyte undergoes two divisions, resulting in four spermatids with 13 chromosomes each. Therefore, a sperm cell would also have 13 chromosomes.
How many sperm are formed from one primary spermatocyte?
One primary spermatocyte undergoes meiosis to produce four sperm cells.
What are the 5 steps of spermatogenesis?
The five steps of spermatogenesis are: 1) Spermatogonium division, 2) Primary spermatocyte division, 3) Secondary spermatocyte division, 4) Spermatid formation, and 5) Spermatozoa maturation.
How many chromosomes does a cell of the testes have?
A cell of the testes, called a spermatocyte, has 46 chromosomes in humans. This includes 23 pairs of chromosomes, one set inherited from each parent. During the process of meiosis, the number of chromosomes is halved to 23 to create sperm cells.
How many sperm produced by one spermatocyte?
4

What are chromosomes that match from the sperm and egg?
homologues
How many sperm are formed from one primary spermatocyte?
One primary spermatocyte undergoes meiosis to produce four sperm cells.
Sperm are produced within the testes by the process of?
Spermatogenesis- takes place in the seminiferous tubule of the testesIt is the form of gametogenesis taking place in males and utilises the two forms of nuclear division to produce a haploid gamete.A cell from the germinal epithelium (2n) divides by mitosis to form the spermatagonia (2n), which then develops into the primary spermatocyte (2n). The primary spermatocyte divides by meiosis 1 to form the secondary spermatocyte (n), which divides by meiosis 2 to become the spermatid (n). This spermatid develops and matures in the epididymis to form the final spermatazoon (or just sperm)Germinal epithelium --> Spermatagonia --> Primary spermatocyte --> Secondary spermatocyte --> Spermatid --> Spermatazoon

What is anatomical name for a sperm cell?
spermatocyte
What is the anatomical name for a sperm cell?
spermatocyte
The cellular product of spermatogenesis is four?
The cellular product of spermatogenesis is four haploid spermatids that will eventually mature into sperm cells through a process called spermiogenesis. Each spermatid contains half the normal number of chromosomes and is produced from a primary spermatocyte through two rounds of cell division.
How many sperm produced by one spermatocyte?
4

If the body cells of humans contain 46 chromosomes a single sperm cell should have?
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.
Why do you get sperm?
I get sperm for my biological purpose. That is, to sexually reproduce. If you are a male; I would assume that's the same reason why you get sperm. If your female; then I'm worried deeply about you. If you're wondering where sperm comes from or how it's made... I can tell you that it's made from the human body. Specifically, by the DNA which provides information to create the sperm cells (like a manual). The making of sperm is called spermatogenesis. Sperm are basically complex cells which simply contain the males genetic code. Sperm cells come from spermatogonium. Spermatogonium contains 46 chromosomes. It duplicates it DNA and divides by meiosis. One cell becomes a Spermatogonium (which will undergo this process again) and another becomes a primary spermatocyte, each cell has 46 chromosomes. The spermatocyte divides by meiosis to produce two secondary spermatocytes, each containing 23 chromosomes. These divide again to provide spermatids, each with 23 chromosomes. Then the spermatids differentiate into sperm cells, all containing 23 chromosomes which will be paired up with 23 others upon fertilization (sex). Spermatogenesis takes place in the testicles.
