| Abstract: | The striking dimorphism of male and female junglefowl may have evolved in large part due to female choice of mates. However, domestic fowl hens consistently chose domestic, not junglefowl, males as well as females in preference tests. Either genetic predisposition to favor junglefowl morphological features over those of the domestic types utilized in these tests was overridden by experience or such genetic predisposition does not exist in the breed we tested. |
