What I would recommend is that you use the alternate images system as a basis for gendering your adoptables. Make each adoptable have a 1 in 2 chance of using the alternate images. Then when you make new adoptables always use alternate images and make the primary images female and the alternates male. That way then you have a 50/50 shot of getting a male or female adoptable.

Then for breeding, simply check if the adoptable is using the primary or alternate images. So, for sample breeding what you could do is check if the user has one adoptable of type x that is male and one of type x that is female. If they do, then they are allowed to breed. :)

Hope it helps,
