In a population of wild squirrels, most of them have gray fur, but an occasional squirrel is completely white. If we let P and p represent dominant and recessive alleles, respectively, of a gene that encodes an enzyme necessary for pigment formation, which of the following statements do you think is most likely to be correct
A) The white squirrels are pp , and the p allele is a loss-of-function allele
B)The gray squirrels are pp , and the p allele is a loss-of-function allele
C) The white squirrels are PP , and the P allele is a loss-of-function allele
D) The gray squirrels are PP , and the P allele is a loss-of-function allele.
