Mudokons live in eusocial environments which is where all offspring come from a queen. Not unlike ants or bees. So technique Abe is neither male or female but asexual.
The only mentioned mudokon queen so far is Queen Sammy; who is, I think, a captive of Vykkers Labs.
For future questions like this I suggest using the Oddworld Questions and Answers thread.
