partial quote
Quote:
All embryos are identical in external appearance for the first eight weeks of gestation, and then several factors nudge the infant toward male or female development. In the seventh week, the embryo has both male and female primordial ducts. In the normal female fetus, the millerian duct system then develops into oviducts and a uterus. In the normal male fetus, the wolferian duct system on each side develops into the epididymis and vas deferens. The external genitalia are similarly bipotential until the eighth week (The reproductive organs and genitals associated with "female" or "male" arise from the same initial (fetal) tissue). Thereafter, the urogenital slit disappears and male genitalia form or alternatively, it remains open, and female genitalia form.
If the egg was fertilized with the x chromosome then the female structures continue to mature, the default system.
However if the y chromosome fertilized the egg then a hormonal switch happens,,, two genes are activated and the female structures are completely dissolved and destroyed and the male organs take their place.
