9. In hamsters, black fur (B) is dominant over brown fur (b) and long fur (L) is dominant over short fur (I). 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. a. What is the probability that the first three offspring will have brown, long fur? b. What is the probability that the first offspring will have black, long fur? c. What is the probability that one of the first three offspring will have black, long fur and the other two brown, short fur?

2.In dogs, there is a hereditary deafness caused by a recessive allele, d. A kennel owner has a male dog that she wants to use for breeding purposes if possible. The dog can hear, but the owner is unsure of the genotype. She does a testcross (crosses it to a homozygous recessive dog), and two of the five offspring are deaf. This means that the male dog A.has the genotype DD B.has the genotype Dd C.is still of unknown genotype since there were offspring of both deaf and hearing phenotypes. D.has the genotype dd
