This value of 58 gave the furthest locus to the right obtained up to that time, since forked is slightly beyond rudimentary. Later, the locus for bar-eye was found still farther to the right, and the locus for fused even farther to the right than bar. A cross was made involving these three gens. A forked (not-bar) fused male was bred to a (not-forked) bar (not-fused) female and gave bar females and males. The F_1 females were back-crossed singly to forked fused males with the result shown in table 41. TABLE 41.--_P_1 bar_ [female] [female] x _forked fused_ [male] [male]. _B. C. F_1 bar_ [female] x _forked fused_ [male] [male].
