Question

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?
unable to be determined
bobtail
bb
normal tail

Explanation:

In genetics, if a trait is dominant (like bobtail, represented by \(B\)), an organism needs at least one dominant allele (\(B\)) to show the dominant phenotype. Recessive traits (like normal tail) are only expressed when an organism has two recessive alleles (\(bb\)). Since the dog's genotype is \(bb\) (two recessive alleles), it will show the recessive phenotype.

Answer:

Normal tail
