So we have two different possibilities and we can test both of these possibilities to see if they actually work. Let's begin by assuming that this individual has this genotype and this individual also has that genotype. So in this particular case we can carry out our punish square. So we basically produce b lowercase b b lowercase b b lowercase b b lowercase b So that means all these individuals, including this one, number seven, is uppercase B, lowercase B. And the same thing is true here. This one is upper case B, lowercase B.
