If entire genome is encoding than mathematically human should have 106 genes but humans have only 30,000 to 50,000 genes this is also a paradoxical feature of genome

ANDROGEN-INSENSITIVITY SYNDROME

These individuals have female external sexual characteristics. Vagina ends blindly and that the uterus, oviducts, and ovaries are absent.

 Inside the abdominal cavity, a pair of testes produce levels of testosterone normally seen in males. 

Woman with androgen-insensitivity syndrome contain an X and a Y chromosome. 

Testosterone bind to an androgen receptor. This receptor is defective in females with androgen-insensitivity syndrome.

The gene for the androgen receptor is located on the X chromosome
