I had a litter of all blue and whites out of a cross between a black and white and seal in white. Should not have had dilutes with this cross. I can’t remember this ever showing up before in SD. I have IGs in RL and would not expect blue from that kind of breeding, had what I thought was a red bred to my seal girl and got one blue pup but turned out dad was really red fawn, so therefore dilute. Just kind of a surprise though with blues in short supply in SD glad to get the color. Anyone else having odd color results?

If this happpened in RL would be doing DNA parentage tests

I don't know. According to your colours setup, it's definitely possible.

Blue is a dilute d/d working on all pigments. It can be carried by blacks who are genetically A/A,D/d and I would think also seal which are Ay/A,D/d. This is the situation depicted by your colour chart.

Your chart seems seems perfectly reasonable in this regard. You need a double dose of the recessive d for it to have an impact. It is very possible for both black and seal to carry the recessive.

With small litters (this is the case I believe with the IG) it has less chance of showing up so it's a little odd perhaps to see 3 of them but not impossible.

Congratulations!
