## Step 1This problem is related to genetics, specifically the inheritance of eye color. The eye color is determined by the alleles of a gene. In this case, brown eyes are dominant over blue eyes. This means that if an individual has at least one allele for brown eyes, they will have brown eyes. Blue eyes are recessive, which means that an individual must have two alleles for blue eyes to have blue eyes.## Step 2Given that Billy Bob and Alicia both have blue eyes, they each have two alleles for blue eyes. When they have a child, the child will inherit one allele from each parent. Since both parents have blue eyes, the child will inherit two alleles for blue eyes, and thus will have blue eyes.## Step 3However, the child has brown eyes, which means that the child must have inherited at least one allele for brown eyes. This is only possible if Billy Bob is not the biological father, as he does not carry the allele for brown eyes.
