Both of the individuals don't show that disease phenotype and so they're lowercase B, lowercase B. So this actually works out. What about this case? Well, notice that this individual cannot be uppercase B, uppercase B, because if it were uppercase B uppercase B, what that means is these two individuals would be heterozygous and so that is not true. What about if it's this? Well if it's this, then we have BB, we have lowercase B, lowercase B, and so what this would produce is it would produce 50% heterozygous, so 50% heterozygous and 50% homozygous recessive.
