Answer - 
1. BB
2. bb
3. Bb
4. B = is the black dog is dominant over the b = brown dog
5. Lower case b 
6. Bb
7.
   bb = brown dog
   Bb = black dog
   BB = black dog 

Reasoning - Reason is since it said black dog is dominant automatically you will know that it will be the uppercase B and since the less dominant in this case the brown dog it will be lower case. In addition automatically if the one uppercase is combine with the lower, the dominant will always be that color which is the black dog. (Confidently its correct) :)
