An explanation for this theory is that the X-chromosome simply inactivates in the presence of another X-chromosome; this causes XX-chromosome humans to have a lower frequency of the regulatory gene given that both X and Y chromosomes have an equal frequency of the regulator and so the expression of the male trait is prevented from appearing in the phenotype.

Genome Research. How many sex chromosomes are in humans? Fish and amphibians, for example, have genetic sex determination but their sex can also be influenced by externally available steroids and incubation temperature of eggs.
