Why was funk dominated by male singers and disco by female singers?

Answer 1

Like most things, funk music was male-dominated at its start. Disco, however, was a reaction to the exclusionary nature of funk as an art, as well as to the exclusionary nature of other types of music prevalent at the time. As such, it was created by those marginalized groups: LGBT individuals, African-Americans, Latinos, and women. Disco, then, was more female-dominated than funk, and funk remained dominated by the mainstream group: white heterosexual men.
