Genetics

Question
I have a 2 year old fawn boxer "in season".  We have many people
wanting a pup from her. We prefer her coloring but some people want
"brindle"  pups.  If we pick a brindle colored stud, will we get all brindle
pups? I just love the fawn and don't know what the heck to do!

Answer
It depends on his brindle gene.

There is a dominate brindle which is referred to as double brindle and a single brindle is not dominate.

A dominate brindle gene and a fawn will produce 100% brindle pups that will be single brindle gene (because of the fawn parent).

Fawn and single brindle gene will produce 50% and 50% .

So it will depend on the gene of the brindle sire.

Here is information explaining it all for you:
