Imagine that you went to the pet store and bought two black guinea pigs that are known to be heterozygoues (Bb). You also kno whtat black fur (BB) is dominant over white fur (bb), and a that a lethal recessive allele is located only one cM away from the recessive (b) allele. You decide to start raising your own guinea pigs, but after mating these animals several times, you discover they only produce only black progeny.  a) How would you explain this result b) what is the probability of your two black guinea pigs producing white offspring?  c) If an average mating produces 10 offspring, how many matings would it take to produce a white offspring?
