We inherit 50% of our genes from our parents. If you inherit a Y chromosome from your father the baby will be male and if a X chromosome is inherited then the baby will be female.
for the first few weeks of prenatal development, foetus' develop identically
after 6 weeks, the sex organs start to develop. They develop identically initially in both males & females, with the only difference being the Y chromosome.
A gene in the Y chromosome produces SRY protein which is a testes determining factor.
After this, the role of genes ceases in development. The role of the Y chromosome is to make sure the male sex organs develop and are subject to male hormones.
Testosterone is the hormone that causes physical differences between males and females.

scientific and measureable eg hormone levels
support from David Reimer, even after being raised as a female he still felt male
challenged by the learning approach which would argue your gender development comes from observing and imitating
challenged by the psychodynamic approach which would argue your gender development comes from identification with the same sex parent.
studies on animals, such as Pfeiffer, may not give us a true insight as humans are more complex.
