ANSWER: Hi Angel

Are you line breeding, in breeding, out crossing?  What are the colors for three generations on both sides?

QUESTION: They are not same lines... Both bostons but not family. Thanks

Answer
So they are out-crossed for generations then.

Do you know the colors of generations?  All that contributes.

Black is a dominate color.  There are three basic colors. Black, Brown and White.   All colors are diluted or come from those three basic colors.

You will may get predominately dark colors (black, brindle) but you may get a few throw backs.  Depending on which lines are stronger.
