Number of chromosomes in primary spermatocyte of frog is ???
Answers
Spermatocytes are a type of male gametocyte in animals. They derive from immature germ cells called spermatogonia. They are found in the testis, in a structure known as the seminiferous tubules.[1] There are two types of spermatocytes, primary and secondary spermatocytes (Figure 1). Primary and secondary spermatocytes are formed through the process of spermatocytogenesis (Figure 3).[2]
Primary spermatocytes are diploid (2N) cells. After Meiosis I, two secondary spermatocytes are formed. Secondary spermatocytes are haploid (N) cells that contain half the number of chromosomes.[1]
All male animals produce spermatocytes, even hermaphrodites such as C. elegans, which exist as a male or hermaphrodite. In hermaphrodite C. elegans, sperm production occurs first and is then stored in the spermatheca. Once the eggs are formed, they are able to self-fertilize and produce up to 350 progeny.[3]
