Are there only two genders?
Many people use the terms “sex” and “gender” interchangeably, but keep in mind that the two don’t have the same meaning.

As already stated, gender refers to the socially constructed roles and behaviors that are assigned to people. On the other hand, sex is referred as to the biological characteristics of a person, such as their sex organs, hormones, and chromosomes.

It’s safe to say that science recognizes three sexes: male, female, and intersex. However, gender is not made up of binary forms. Instead, it’s a wide spectrum.
What does it mean that sex is a spectrum?  Does this mean that there is a scalar between to poles (ie 0 and 1) with each pole representing one of the genders?  Does this mean that someone could be 80% female and 20% male – or 40% male and 60% female?
