29.1.1 Sex Differentiation & Reproduction of Crustacean
The genetic composition of the individual decides whether or not the androgenic gland will be differentiated from this primordial gonadal tissue. In the male, the androgenic gland develops and its hormonal activity results in the production of remaining gonadial tissue into a testis. In the female the androgenic gland does not develop and gonad becomes the ovary. There are many experiments in which the androgenic glands are removed from the male and the male will either become sterile or functional female due to the dominance of the estrogens |
