i am not compleatly possitive on this, is there a specific mateing or genetic trait in mamals (rabbits) that can cause sexlinkage like in birds? i am guessing the awnser is prolly No as i have not heard of any. just thought i would ask.

There probably is, but I don't know of any that are visible in the offspring. For example, in humans there is hemophilia and colour blindness, but they don't affect what a person looks like. There are probably ones like this in other mammals as well.

your right i had forgotten about thoughs in humans, the more i thought about it after i had posted i realized that more than likely there isnt auto sexing or sexlinkage genes that (at least readily available) (who knows what some lab rats cary) are present in most if not all mamals, and really i am not sure of a need for it really, as mamals easily sexed by exterior genetalia unlike birds,

I haven't heard of anything involving rabbits, but what about cats? Aren't the gingers almost always males, and the calicos almost always females?

dont know about the gingers, not compleatly sure i would know what color to call ginger, but calico are something like 99.9% female, we used to have some calico cats on the farm back in kansas, every litter would have at least one, and we were always looking for that non existant male calico lol, so i think (at least from my experiance) calico cats are ALWAYS female.

The mammals you guys are forgetting about are some breeds/species where males are horned, ANTLERED or tusked while females are not!!! Calico is a sex link in cats, calico males are few, and sterile. In humans-- facial hair is normally a sex link-- but it is also very hormonally dependent. In fact, hormones make it posible for the genitalia of any mammal to differentiate in utero--- otherwise, all mammals would be physically, at least- female! It would be very interesting to see if someone could develope a sex link coloring or marking in a rabbit---
