Fig. 2. Gonadal development during Yntema stages 15, 17, 19, and 25 when incubated at the MPT (26°C) or FPT (32°C). Location of the gonad at Yntema stages (a, b) 15 (black arrows), (c) 17 (MPT), (d) 17 (FPT), (e) 19 (MPT), (f) 19 (FPT), (g) 25 (MPT), and (h) 25 (FPT). C = cortical region or outer layer of tissue immediately below the epithelium; F = ovarian follicle; M = medullar region or the inner region of the gonad which is distinguishable from the outer region; SC = medullary sex cord; ST = seminiferous tubule; an asterisk indicates an area with germ cell division; a star indicates an area with cortical development.
