Super Duper Free Extra Credit

So I was given these two pictures.


And was asked to determine the phenotype of the father of these cute pups. Soooo what we know...

There are 12 puppies.
The Mother is a yellow.
5 of the pups are brown.
The remaining 7 are black.

So right off the bat, we know that mom has to be:
    eebb
    eeBB
    eeBb
We also know that the offspring are about half brown half black. So we have to find a pair of parents that result in half:
    Eebb / EEbb
and half:
    EEBB / EEBb / EeBb / EeBB

So after fiddling around with a few Punnet Squares, I found that:




The Fathers Phenotype must be EEBb.
