(c) Stage III; oocyte with finely granular yolk/cytoplasm. Yolk polarity and migration of nucleolus to periphery of nucleus observed. (d,e) Stage IV-V; oocyte grow tremendously in size. (f) Stage VI; Final stage (Egg). oo; oocyte, mf; mesentery filament, n; nucleus, gv; germinal vesicle, gyd; granular yolk disposition, e; egg.
