[Cerra]

I have a DTW (female) and a black (male) and all I get from them is
blacks and whites...I'm not sure if the whites are DTW or not, they are
definitly PEW. I guess this is sort of adding to what is already said,
it just depends on the recessives...BTW what are the genes of my gerbs
knowing this? Thanks in advance
