Question

processs of oogenesis ​

Answer 1

Oogenesis is the process of the formation of a mature ovum from the oogonia in females. It takes place in the ovaries. During oogenesis, a diploid oogonium or egg mother cell increases in size and gets transformed into a diploid primary oocyte.

Answer 2

• It is defined as the process by which ova or female gametes are formed.

The process in brief:

⋆ The diploid germ cells that have the potential to develop into ova are called oogonia. 

⋆ this occurs in the ovaries.

⋆ during oogenesis the oogonia increases in size.

⋆ it becomes diploid primary oocyte. { oocyte -female germ cell capable of doing meiotic divisions in order to form ova }

⋆ when first meiotic division happens, two unequal haploid cells are formed. { smaller cell - first polar body and larger cell - secondary oocyte. }

⋆ The secondary oocyte undergoes second meiotic division.

⋆ giving rise to a polar body and ova.
