Sex and gender are constellations:
"Many people, including Dawkins, believe sex and gender are a straightforward binary. You’re either male or female, a man or a woman, end of story.
But if that were the case, it should be easy to come up with a rule that tells you which sex a person is. However, that turns out to be not nearly so simple. The more you look, the more you find that any such rule is fraught with complications, exceptions and judgment calls."
