Last updated: 10/20/2023

The recessive alleles for cinnibar eyes cn and vestigial wings vg identify two autosomal genes on the third chromosome of Drosophila melanogaster When females heterozygous at these two genes cn cn vg vg were crossed with cinnibar eyed vestigial winged males the following classes and numbers of progeny n 1000 were obtained Wild type eye color wild type wings 42 Wild type eye color vestigial wings 464 Cinnibar eye color vestigial wings 38 Cinnibar eye color wild type wings 456 Based upon these results the map distance between the cn and vg genes is estimated to be 4 map units 8 map units 46 map units 92 map units
