Sco phenotype

[Haojiang]

Hi,dear all,

I have a stock male is FM7a/>; Sco/Cyo, and female is c(1)M3, y[3]/>;
Sco/Cyo. But for some mysterious reason, I can not see any phenotype
of Sco in the female. And in the male, I only can see there were more
bristles, usu. the humorals. After I crossed FRT;; female with FM7a/>;
Sco/Cyo, I can not see any phenotype of Sco in the F1. Can any one
provide any experience on the Sco phenotype?

Thank you!
