An example of multiple alleles is seen at a locus that determines the feather pattern of mallard ducks. One allele M produces the wild-type mallard pattern. A second allele M ^ R produces a different pattern called restricted, and a third allele, m ^ d , produces a pattern termed dusky. In this allelic series, the dominance pattern is M ^ R M m ^ d . In a cross between restricted and mallard ducks it was found that o

Options
