An example of multiple alleles is at a locus that determines the feather pattern of mallard ducks. One allele, M, produces the wild-type mallard pattern, MR, produces restricted, and a third allele, md, produces dusky. In this allelic series, dominancy shows MR >M > md

If a cross between  MR md X M md, What proportion of progeny will be restricted?
