If its going to take an aro a few years to mature, along with the few years to partner up FOR LIFE, they are not going to be breeding offspring with parents. Quite possible for them to be breeding sibling offspring, but definitely won't be a big chance at all. Just the scale difference is already a genetic difference lol...theres a reason why humans cannot breed with other species no matter how similar they are unless they are genetically tampered with.
