WL litter.. all Bi's?! - Page 1

Just curious how often the entire litter can be Bi colored? 7 pups in total.

All bi?! Dam is sable sire is bi. 

Anyone else have this happen before?

Could happen, Dam must be having recessive bi gene. Statistically bi offspring should be 50%. In your case you got all offspring bi but when repeating same mating several times you will most probably get sables too.

P.S: Dam could have a recessive Solid Black gene, but lesser probability.

All Probabilities:

Sable Dam might have either Bi or Solid Black recessive.

(Sable + Bi), or (Sable + Solid Black)

Bi Color Sire might have either

(Bi + Bi), or (Bi + Solid Black)

So probabilities are like this:

1. Dam (Sable + Bi), Sire (Bi + Bi) then offspring 50% Sable & 50% Bi

2. Dam (Sable + Solid Black), Sire (Bi + Bi) offspring 50% Sable & 50% Bi

3. Dam (Sable + Bi) Sire (Bi + Solid Black) offspring 50% Sable & 50% Bi

4. Dam (Sable + Solid Black), Sire (Bi + Solid Black) offspring 50% Sable, 25% Bi & 25% Solid Black

tThank you so much for the feedback! Unfortunately it's not my litter. But hope to possibly get a pup from this litter. Great working lines are there so I'm excited to see the full outcome of drives in these pretty pups! 

Are you absolutely sure the sire is bicolor? Can you please post pics of both parents and pedigrees?

And unless they change as they get older they look like all BI's

I suspect the bicolor sire does not carry the black recessive--just bicolor/bicolor. (Or, for the purists, tanpoint/tanpoint with no creeping tan gene.) The dam is most likely sable/black. Luck of the draw -- all the puppies got the black gene from mom and the bicolor gene from dad. In another litter, you'd probably get some sable/bicolor pups, phenotypically sable.
