A kidney-bean shaped eye is produced by a recessive gene k on
the third chromosome of Drosophila. Orange eye color, called
“cardinal”, is produced by the recessive gene cd on the same
chromosome. A recessive allele e produces ebony body color at a
third locus on that chromosome. Homozygous kidney, cardinal females
are mated to homozygous ebony males. The dihybrid F1 females are
then testcross to produce the F2. Among 4000 F2 progeny are the
following:
1761 Kidney, Cardinal
97 Kidney
1773 Ebony
89 Ebony, Cardinal
128 Kidney, Ebony
6 Kidney, Ebony, Cardinal
138 Cardinal
8 Wild type (+)
