A bobtail (shortened tail) is dominant over a normal tail in dogs . What would the phenotype of a dog be if its genotype is bb? Normal tail Bobtail Bb Unable to be determined

## Step 1<br />In this problem, we are dealing with the principles of genetics, specifically the concept of dominance. The problem states that a bobtail (shortened tail) is dominant over a normal tail in dogs. This means that if a dog has at least one allele for a bobtail, it will have a bobtail phenotype.<br /><br />## Step 2<br />The genotype of a dog is represented by two alleles, one from each parent. In this case, the dog's genotype is 'bb', which means it has two recessive alleles for a normal tail.<br /><br />## Step 3<br />Since the dog has two recessive alleles, it will not have the dominant bobtail phenotype. Instead, it will have the recessive phenotype, which is a normal tail.
