TABLE 36. Linkage of vermilion, bar, and fused with balanced viability. 



Some additional data bearing on the linkage of vermilion and fused 

 were obtained. Males of (red) fused stock were bred to vermilion 

 (not-fused) females, and gave wild-type females and vermilion males, 

 which inbred gave the results shown in table 37. 



The percentage of cross-overs between vermilion and fused is here 27, 

 which is in agreement with the 26 per cent of the preceding experiment. 



The converse experiment, namely, red (not-fused) females by 

 vermilion fused males also gave, when the wild-type daughters were
