Answer :
In the tertiary follicle, the primary oocyte enlarges, completes its first meiotic division, and produces a big haploid, secondary oocytes, and a first, little polar body.
The primary follicles develop into Graafian follicles that are fully developed in the ovary.The early follicle follicle develops from the primary oocyte, and the secondary follicle, which undergoes the first meiotic division, develops from the primary follicle later. The subsequent transformation of the secondary follicle into a graafian follicle, which houses the secondary oocyte. The graafian follicle houses a supplementary oocyte, to sum up.
The oocyte and the follicular cells that surround it make up the primordial follicle. The extra DNA from the egg that was created during meiosis 2 is contained in the second polar body, a tiny cytoplasmic exclusion body.
