How to breed out c-p linkage?

Post by Mrs. Beach on Mon Mar 04, 2013 4:10 pm

I'm just coming to the conclusion that my foundation buck of the Victorian Line (typey tricolors), Grimbling *A/a c^e/c^e s/s), is a tumor-carrier. I have another very typey buck, Toilet Paper Boy (c/c p/p, c-p linked, Spl/*), and a very typey doe, Galatea (also c/c p/p, c-p linked, Spl/*).

I was thinking I could breed Galatea to Grimbling (cross f1"s, the backcross to Toilet Paper Boy who would be my new foundation buck) to try to breed tumors out of the Victorian Line, but would that cause p to be linked to c^e, or would it stay linked only to c?

I don't want (or c)! I need advice!

The c-gene that is currently linked with the p-gene will stay linked unless you manage to unlink them. It's totally random, and not super-common. Some folks say it hardly ever happens, while other folks have it happen more often. If it does unlink from your c, it would attach to the ce, yes. Chances are good that it wouldn't, however.

Also, sorry that it took me a bit to reply. I haven't been on the computer much because life's been pretty hectic. I hope this answer is still useful to you.
