Drosophila females heterozygous for three recessive X-linkedmarkers, y (yellow body), ct (cut wings), and m (miniature wings),and their wild-type alleles were crossed to y ct m males. Thefollowing progeny were obtained:
1 YELLOW, CUT, MINIATURE = 30.
2. Wild-type = 33
3. yellow = 10
4. cut, miniature = 12
5. miniature = 8
6. yellow, cut = 5
7 yellow miniature = 1
8. cut = 1
1. Determine the order of these genes
2. Calculate the map distances between the genes
3.determine the coefficient of coincidence and the interferenceamong these genes
