Re: Genetics of the Spotted (Sp) allele

[Iva English]

Hi,

In my spsp x SPsp litters I have come up with about half spot and half non
spot in all litters without white pups.

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'.
