Fluffernutter labradors are identical to earth labradors in every way, except that they grow marshmallows instead of fur. the three possible types of marshmallow skin are: a. black (tastes like licorice); b. chocolate (tastes like chocolate); c. yellow (tastes like vanilla).there are two genes that control for this phenotype, acting in a recessive epistatic manner. the two-locus genotypes that correspond to the phenotypes are: a_b_ (codes for licorice); aab_ (codes for chocolate); __bb (codes for vanilla).note that the alleles at the two loci are: a (dominant), a (recessive), (locus 01)b (dominant), b (recessive). (locus 02)if two doubly heterozygous licorice labs mate, what is the expected proportion of vanilla fluffernutter progeny? a. 1/8.b. 3/4.c. 1/2.d. 1/4.e. 9/16.
