No kidding, 'genders' can be anything. ‘Two sexes’ with rare exceptions is the rule.If you have to wonder, there is no way anyone can explain it to you.
For example, in the US there is a highly poisonous snake, the copperhead, that can fertilize it’s own eggs. The situation is known as parthogenesis. There are at least ten other animals which can be classified as “other”. Some people may not like to admit it, but there are more genders than male or female.
