Eyes of heterozygote reduced at anterior edges. Expression variable; in extreme cases, eye size about one-third normal. kD/k1 more extreme than k1 homozygotes. Eyes of homozygote reduced about as much as kD/k1 but occasionally one or both eyes missing; antennae usually slightly deformed with thickened aristae. RK1.
