Fig. 128. — Linkage map for Drosophila melanogaster, showing .serial order of many of the 

 known genes as determined by genetical methods. Letters in parentheses indicate portions 

 of fly in which characters appear: B, body; E, eye; H, hairs; W, wings, .\rrows indicate 

 kinetochore position. Genes in chromosome IV are very closely linked. Positions of 

 genes in F-chromosome not well determined. {Adapted from T. H. Morgan, A. H. Sturte- 

 vant, and C. B. Bridges and from C. Stern.)
