Tests for linkage and other interactions in the honey bee

No linkages were found in 31 new combinations of visible mutants, nor in 5 new combinations with the X locus, conducted mainly with eyeless (e), garnet (g), short (sh), truncate (tr), and wrinkled (wr). Eyeless was epistatic to eye colors; cream (cr), and ivory (i) were epistatic to garnet (g). Selective mortality was invariable with e, sh, and tr, and occasionally with bl, cd, and g.
