H-Y antigen and the growth of the dominant gonad.
The evolutionary conservation of H-Y antigen and its expression in the heterogametic sex regardless of whether this is male or female must mean that the antigen is associated with a common denominator underlying the development of mammalian testes and avian ovaries. It is suggested that one such common denominator is an enhanced growth rate of the dominant heterogametic gonad at a critical stage of its development.
