... phenotype as heterozygotes but are lethal as homozygous dominants. When Curly and Plum are separately crossed to wild-type flies and the F1 mutant progeny are intercrossed, what will the resulting phenotypic ratio be? #3 Many matings between a dark, short-haired dog and a dark, longhaired dog yield ...
