So let's see, assumption number two is it is autosomal recessive. Let's see if that actually works out. So autosomal recessive and what that basically means is the only time that we express a disease phenotype, a phenotype that expresses that disease is when both of those autosomes contain a gene that is recessive. And so this female individual must be lowercase B lowercase B, and this male must be lowercase B lowercase B. Now what about these two individuals? Well, they can either be uppercase B uppercase B, or they can be uppercase B lowercase B.
