You find two different notch-winged fruit flies in your normally smooth-winged collections. After the two notch-winged lines are bred for several generations to make sure they are genetically homozygous, you want to find out if the recessive mutations causing notched wings are at the same or different loci. You cross the two notch-winged lines. What offspring do you expect if the mutations are allelic (at the same locus)? O all smooth O all notched O 1 notched: 3 smooth O 1 notched : 1 smooth
