In humans, at the end of the first meiotic division, the male germ cells differentiate into the:
The correct option is B Secondary spermatocytes
The correct option is B.
Explanation of Correct option:
- Each primary spermatocyte undergoes first maturation division which is reduction division i.e., the first meiotic division which gives rise to secondary spermatocytes.
- The secondary spermatocytes are haploid daughter cells with n number of chromosomes.
- Two secondary spermatocytes are formed.
Explanation of Incorrect option:
Option a:
The secondary spermatocytes undergo second meiotic division to form four daughter cells known as spermatids.
Option c:
During the growth phase, the spermatocytes grow in size, accumulate nutrients, and replicate DNA to be called primary spermatocytes.
Option d:
The primordial germ cells of the germinal epithelium undergo mitotic division and give rise to undifferentiated germ cells called spermatogonia.
Final answer: In humans, at the end of the first meiotic division, the male germ cells differentiate into the secondary spermatocytes.
