Fig. 119. Diagram show- 

 ing the location, in the 

 four paired chromosomes 

 of Drosophila, of the 

 genes for various Men- 

 delizing chiiracters, as de- 

 termined by Morgan and 

 his pupils. The X-chro- 

 mosome is at the left. 

 All characters there enu- 

 merated are sex-linkec^. 

 The numerals indicate 

 the supposed relative dis- 

 tances of the genes from 

 the upper (zero) end of 

 each chromosome as de- 

 termined hy linkage 

 strengths in crosses. (.\f- 

 ter Morgan, Sturtevant, 

 Muller and Bridges.)
