Which of the following conclusions about the genotypes of the parental mice is the ONLY possibility for the given outcomes? Select one: a. If any of the offspring have white fur, the parental black mouse genotype is heterozygous. b. If all the offspring have white fur, the parental black mouse genotype is homozygous c. If all the offspring have black fur, the parental black mouse genotype is homozygous. d. If any of the offspring have white fur, the parental white mouse genotype is heterozygous.
