According to their lore, they're hermaphrodites and have both functioning reproductive organs. Gender is completely up to the expie in question, they could even be genderless. (How very woke)
where does one get such lore? plus, I wouldn't say it's woke. hermaphroditism occurs in a handful of real creatures, so why not in a genetically engineered creature?
this train of thought reminds me of Jurassic Park, and life, uh, finds a way.
