Question

What is the ploidy of primary spermatocytes?

Answer 1

Primary spermatocytes:

1. Spermatocytes are a type of male gametocyte in animals. They originate from immature germ cells called spermatogonia.
2. They are found in the testicles in structures known as seminiferous tubules.
3. There are two types of spermatocytes: primary spermatocytes and secondary spermatocytes. Primary and secondary spermatocytes are formed through the process of spermatogenesis.

Ploidy of primary spermatocytes:

1. Primary spermatocytes are diploid (2n) cells. After meiosis I, two secondary spermatocytes are formed. Secondary spermatocytes are haploid (N) cells that contain half a chromosome.
2. In all animals, males produce spermatocytes, even hermaphrodites such as C. elegans, which exist as males or hermaphrodites. In hermaphroditic C. elegans, sperm production occurs first and is then stored in seminal vesicles.
3. Once the eggs are formed, they can self-fertilize and produce up to 350 offspring.
4. There are 23 chromosomes in it.
