Thus, saying all mammals start as female based on a lack of gonadal development and the expression of the X gene only isntcorrect in technical terms, but it is essentially correct in laymans terms for to illustrate the general point in casual conversation (that is, for the first few weeks of gestation only the X gene expresses). When the Y gene expresses males become males, until then, only the X gene expresses and we are all essentially females (if you judge female / male by sex organ rather than genetic code). You can touch the testicles which have become little lumps in their pelvic regions. They perform lots of activities like seducing and chasing the female pandas.
