Assume that investigators crossed a strain of flies carrying the dominant eye mutation Lobe on the second chromosome with a strain homozygous for the second chromosome recessive mutations smooth abdomen and straw body. The F1 Lobe females were then backcrossed with homozygous smooth abdomen, straw-body males, and the following phenotypes were observed: 

   smooth abdomen, straw body   820
   Lobe   780
   smooth abdomen, Lobe     42
   straw body     58
   smooth abdomen   148
   Lobe, straw body   152
   
(a) Give the gene order and map units for these three loci.
(b) What is the coefficient of coincidence?
