Problem
In dogs, black coat (B) is dominant to brown coat (b). Another dominant allele will produce long tails (L), while the recessive allele will result in short tails (l). Conduct a cross between a dog with a brown coat and homozygous for long tail to a dog who is heterozygous for both traits.
i. What are the genotypes of the parent dogs?
ii. List the phenotypic ratios of the offspring.
