Gender is usually considered indicative or coupled with cultural behavior and performative behavior, i.e. in the U.S. barbie dolls are 'toys for girls'. Sex begins and ends at the biological level and is strictly related to the organs and biological makeup you have and what you can do with those. I know less about how sex isn't binary, but in the case of gender it's fairly evident these days. At least that's how I've understood it in layman's terms and with my very basic knowledge--it's very complex, as with anything worth studying. The seminal text on the issue in the eyes of many is Judith Butler's Gender Trouble--If you truly are serious about wanting to learn about this stuff I suggest you check it out.
