ANNA R. WHITING. 



light males produced in classes d and e give still further evidence 

 of biparental inheritance. Their mothers were orange or ivory, 

 fathers light. They resemble their heterozygous sisters as their 

 ocelli are lighter in color than those of males from light stock. 



TABLE I. 

 CROSSES PRODUCING BIPARENTAL MALES. 



In section II. are data on crosses where parents differ in wing 

 character, locus R, but are similar in eye color. Biparental males 

 can be readily recognized by their non-reduced wings. These are 

 of interest since they show that the chromosome carrying R acts 

 in the same manner as those containing O and D.
