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 expermient. 



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

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