"Seven loci (y, w, bi, v, m, s, B) looked up by symbol; 1915 map distance for each of the 21 pairs from the book's percentages versus genomic distance between gene midpoints (Mb); Spearman rank correlation." . . "Measured: 0.9662 Spearman rho between 1915 map distance and genomic distance over 21 locus pairs (n = 21, Pearson r 0.972; 7 loci on one chromosome). Interpretation: The 1915 map values are the ones quoted in the claims file from the book (yellow-white 1, white-bifid 5, yellow-bifid 6, white-miniature 33, miniature-Bar 22, vermilion-sable 10, sable-Bar 14), not FlyBase's recombination_loc column, which for most genes is interpolated from cytology and would be circular. The test is one chromosome and seven loci: it tests the law where Morgan stated it, not genome-wide." . "Claim test of morgan1915-04: supports, confidence 0.8" . . .

Any of the seven loci not found in the map table with an X-chromosome sequence location: inconclusive." . "Seven loci on the X only: it tests the law where Morgan stated it. Genome-wide, recombination rate varies along chromosomes (hotspots, centromere suppression), so the relation is monotone, not linear." . "The 1915 map values come from the book's quoted percentages, not from FlyBase's recombination_loc column, which is largely interpolated from cytology." . "sable and Bar are resolved through the FlyBase synonym table to Ype (Yippee) and B-H1 (BarH1); the Bar mutation itself is a duplication of 16A with no single coordinate, so B-H1 stands for its position." . "Over the 21 pairs of the seven loci, Spearman rank correlation between 1915 map distance and genomic distance (midpoints of FlyBase sequence locations on X, Release 6) is >= 0.90: supports." .
