#Unit 8. Inheritance Biology

The type of plumage found in mallard ducks is determined by three alleles at a single locus: MR, which encodes restricted plumage; M, which encodes mallard plumage; and md, which encodes dusky plumage. The restricted phenotype is dominant over mallard and dusky; mallard is dominant over dusky (MR > M > md). The expected phenotypes and proportions of offspring is 3/4 restricted, 1/4 mallard by which of the following crosses?
