I just thought I would throw that out there, since nothing is done on the Akeeans yet. Most birds of prey, according to wikipedia, have significantly larger females than males and I thought it would be interesting if that was reflected in the federation's military and society.
Females, for example, would form the bulk of the military and hold many of the key positions within the Federation while males would play a far more subservient role, owing the militaristic nature of the society.
