Deafness in cocker spaniels is inherited. The allele for deafness (d) is recessive to the allele for hearing (D). Two cocker spaniels that are heterozygous for hearing are mated together. What is the chance that a puppy will be deaf? 0% O 25% 50% O 100%

In dogs, the color black is dependent upon the dominant allele B and white upon the recessive allele b. If two heterozygous black dogs mate, what genotypes and phenotypes may show up in the F1 generation?

In hamsters, black fur (B) is dominant over brown fur (b) and long fur (L) is dominant over short fur (l).  A black, long furred female whose mother had brown fur and whose father had short fur is mated with a black, short furred male whose father had brown, long fur.  What is the probability that the first three offspring will have brown, long fur? What is the probability that the first offspring will have black, long fur? What is the probability that one of the first three offspring will have black, long fur and the other two brown, short fur?
