Can ants interbreed

As a general rule, ants cannot interbreed because of the way in which they breed, letting out the young ants in large swarms to mate, and with their bodies not fitting together well enough for mating. Also, like most species, their genes and chromosomes generally are not enough like those of other ants to let them produce live young.

Furthermore, although it COULD happen that an ant could lay a female egg that is a hybrid, male eggs come only from one parent, the mother, so a mating could not produce a male anyway. Most of the female eggs laid turn into non-breeding workers too, so most hybrids couldn't breed in their turn.
