Fig. 115. 

 Inheritance of the white-eyed character in Drosophila. The gene 

 for white eye is carried by the X-chromosome represented here 

 by an open rod (w). The normal allelomorph to the "white-eyed 

 gene," namely, the "red-eyed gene" is carried here by the black 

 rod. The Y-chromosome is stippled.
