Dumbo Odd Eye Merle Rat

[Michelle.C]

I feed fancies if necessary, they are all just the same animal, the only difference being appearance. I produce blues and minks and a LOT of other colours here in the Los Angeles area, but the only mouse/rat show I've ever been to was pathetic. Hopefully with all the interest in the recent past that will improve.

Rat Genetisists, what would I get from that Merle to solid black females whose father was blue?

Depends on the recessives the grandsire and granddam were carrying. We will assume the grandsire is aagg (American Blue) and granddam is aa (Black). So that would make the Black female aaGg, so aaGg x aammPepeMeme = aa (Black) carrying Mink. Some will be unexpressed Pearl, some will be unexpressed Merle, some will carry American Blue. But if the black female is carrying other recessives, you could get some Mink based, etc. And if the Pearl Merle buck had parents that carried Blue, you can expect Blue based.

It's hard to give an accurate answer without a three generation pedigree, even then, it's just a guess. Rat Genetics are difficult because of all of the recessives that lurk.

Hold back the does (females) and breed them back to their sire. Should give you some Pearl Merles, if he's Pearl Merle.
