From these two models, the study of the development gonadal in different species of birds will help to elucidate variations in the patterns of conztitucion gonadal in vertebrates. Los argumentos intuitivos e informales conservan una claridad apropiada.
Th e results obtained show that in Columba livia, unlike the other species studied, folliculogenesis begins after hatching, and raising new questions about the mechanisms of control of folliculogenesis.

In the birds, the gonads are organized and differentiate to dividing a couple of genital combs, which are constituted by Cells Germinate Primordial CGPsof origin extra-gonadal.
The reproductive cycles of males and females, the existence of sexual dimorphism and bodart male’s vocalization period were analyzed. Remember me on this computer.
