Brindle Boxer

Question
Can you tell me what the difference between a dominant brindle and a non dominant brindle is?

Answer
A brindle boxer may either have two copies of the dominant brindle gene (BB), or one copy of brindle and one of fawn (Bb). A BB (dominant) brindle can produce only brindle offspring, irrespective of whether the dog it is bred with is fawn or brindle. A Bb (non-dominant) brindle can produce both brindle and fawn puppies if it is bred with another non-dominant brindle or with a fawn. See the following diagrams for a pictorial explanation of the average litter results of various breeding pairs.
