What type of breeds are my cats possibly mixed with?

I have two cats, a boy and a girl. The boy is orange (red) and white (no fluffy tail) and the hair underneath him is medium length. The girl is a calico color blend with white (no fluffy tail). They are both considered American Short-hair tabbies but I think they could be mixed with other cat breeds because the male is bigger than a normal male cat for his age (a little over 1yrs). Both cats have white bibs and the bib on the male seems a little more fuller. But it is not as long and full as the Maine Coons and Norwegian Forest cats. We call him lion face, lol. The girl's face reminds us of a lynx (just a tad). His eyes are gold and circular and hers are green and more slanted. Also both cats do not have typical meows. Both more so shrill, whine...talkative. Both also aren't scared of water. I have taken both to the groomers and have gotten good results. The female cat acts like a dog too...follows you everywhere, fetches, hyper, chases her tail (so cute when she does this). The male is a little more laid back. Maybe because he is a little older idk. He's also moody. One minute he wants to be petted and the next he may bite. He is a rescue so maybe he's affected by his previous past, household? But any help in figuring this out would be greatly appreciated so my family and I can know how to communicate a little better with these kitties. Thanks
