[Jacob-list] Statistics on white cats

[Linda]

Got too quick on the send button. Thethought on the genetics list was 
that a Jacob that produced a white lamb when crossbred carries only one 
dominant black (Ed) gene rather than two. The lamb got the E+ gene 
instead ofthe Ed gene. Itseems possible that an all white Jacob lamb 
(all white meaning NO color anywhere including hornsand not an albino) 
may have gotten an E+ gene from each parent. Possible, but maybe not the 
only explanation.

I've never actually seen one with no color, but the pictures I've seen 
have had blue eyes. Do all white Jacobs occur with brown eyes?

I had a white cat with green eyes, who could hear. She was pregnant when 
she was given to me. She had three blue eyed white kittens - all deaf. I 
have a calico cat that might as well be deaf for as well as she listens 
to me.
