Which among the following has 23 chromosomes?

a. Spermatogonia
b. Zygote
c. Secondary oöcyte
d. Oögonia

Answers (1)

The answer is the option (c) secondary oocyte

Explanation: Spermatogonia are diploid (2n) sperm mother cells with 46 chromosomes. A zygote is formed when a sperm (n=23) and an egg (n=23) fuse, resulting in 46 chromosomes. Oogonia are diploid (2n) egg mother cells, also with 46 chromosomes. Each primary follicle in the female ovary contains a diploid primary oocyte arrested in prophase I of meiosis during embryonic development. After puberty, the primary oocyte completes its first meiotic division to form a haploid secondary oocyte with 23 chromosomes.
