There is a 100% chance of this happening.

Explanation :

By bringing the Upper case ‘B’ s down and across into the punnet square, we can already see that they are all going to have the same output/answer. If Bb represents Black and bb represents, say, brown, Bb would be shown in every square. Therefore, it would be a 100% chance of the Guinea pigs being black.
