A male mammal has a seminal vesicles, prostate gland and penis. A femal mammal has a uterus, oviducts, cervix, vagina and mammary glands. The gonadal rudiment has 2 normal options the opposite of other rudiments, for example a lung rudiment can become only a lung. If the Y chromosome is absented then the undifferentiated human gonads will be a female. The appearances of typical males and females do not allow us to differentiate between these hypotheses. But some scientists have been able to differentiate between these two hypotheses by observing certain unusual situations.
