x and y are not dissimilar . In fact they are so similar that y is called x with missing leg. If that is correct then there remain no difference in blue print . if blue print is same how can the structure erected on the basis of this can be different.

Vagina stitched to be scrotum and ovaries dropped down from the tummy as testis........(Ref-man is the extension of woman)
