10. The frizzle fowl is much admired by poultry fanciers. It gets its name from the unusual way that its feathers curl up, giving the impression that it has been (in the memorable words of animal geneticist F. B. Hutt) "pulled backwards through a knothole." Unfortunately, frizzle fowl do not breed true: when two frizzles are intercrossed, they always produce 50 percent frizzles, 25 percent normal, and 25 percent with peculiar woolly feathers that soon fall out, leaving the birds naked. What phenomenon could explain this observation?
A) complementation
B) lack of complementation
C) epistasis
D) lack of epistasis
E) incomplete dominance
F) Synthetic lethality
G) Suppression
