GENERAL HISTOLOGY

Detailed explanation-1: -During the embryonic stage in females, the primary oocyte develops from the gamete mother cell or oogonia . It is diploid in nature. Primary oocytes consist of 46 chromosomes.

Detailed explanation-2: -The diploid egg cell increases in size and transforms into a primary oocyte. The secondary oocyte is produced by the reductional division or meiosis I of the primary oocyte. It has 23 chromosomes.

Detailed explanation-3: -As a result, secondary oocyte contains 23 chromosomes and it is haploid in nature.

Detailed explanation-4: -There are 46 chromosomes in primary oocytes. Primary oocytes undergo meiosis in a process called oogenesis to produce secondary oocytes that contain 23 chromosomes.

Detailed explanation-5: -Spermatogonia, zygote and oogonia have 46 chromosomes each.
