Re: Genetics of the Spotted (Sp) allele

My spotted x Spotted produce very white pups.  To date i've only had one nonspotted pup and it was a nutmeg- other then that, all my black pups have been spotted to some extent when crossing spot x spot and i never had another nutmeg.  Litter size has been normal, so I suspect soemthing interesting going on with the gene (fairly large sample, over several generations) .  Spots on the back are not abnormal, the black spots in the white  probably are mild forms of varigation which can occure in these more-white type of spotted gerbils.  If you keep selecting for the white you can increase it.  Soem of my gerbils look like they are white with flecks of black on their back and tail, and a black patch over each eye.  Very cute.

I have a spot x spot pair that is producing some very spotted pups.  Just wondering how common it is for black spot pups to have large white patches in the middle of the black area on their backs?  I am also getting small black spots in the white areas.  This line also produces Dark Pied Patched Dove pups on a very regular basis. From this pair out of 14 pups I have gotten only 2 non spot pups but the sample size is way to small to know if the gene is 'evolving'.   ~Iva
