ADDITIONAL DATA FOR YELLOW, WHITE, VERMILION, AND MINIATURE.
Considerable new work has been done by various students upon the linkage of the older mutant characters, namely, yellow, white, vermilion, and miniature. We have summarized these new data, and they give values very close to those already published. We have included in the white miniature data those published by P. W. Whiting (Whiting 1913).
Table 62.—Data upon the linkage of yellow, white, vermilion, and miniature(contributed by students).
NEW DATA CONTRIBUTED BY A. H. STURTEVANT AND H. J. MULLER.
Data from several experiments upon sex-linked characters described in this paper have been contributed by Dr. A. H. Sturtevant and Mr. H. J. Muller, and are given in table 63.

SUMMARY OF THE PREVIOUSLY DETERMINED CROSS-OVER VALUES.
The data of the earlier papers, namely, Dexter, 1912; Morgan, 1910c, 1911a, 1911f, 1912f, 1912g; Morgan and Bridges, 1913; Morgan and Cattell, 1912 and 1913; Safir, 1913; Sturtevant, 1913 and 1915; and Tice, 1914, have been summarized in a recent paper by Sturtevant (Sturtevant, 1915) and are given here in table 64. Our summary combines three summaries of Sturtevant, viz, that of single crossing-over and two of double crossing-over.
Table 64.—Previously published data summarized from Sturtevant, 1915.
SUMMARY OF ALL DATA UPON LINKAGE OF GENS IN CHROMOSOME I.
In table 65 all data so far secured upon the sex-linked characters are summarized. These data include the experiments previously published in the papers given in the bibliography and the experiments given here. The data from experiments involving three or more loci are calculated separately for each value and included in the totals.
