ND, not done.
↵a y/y pn cv m f · y⁺ females carrying the indicated third chromosomes were crossed with X^Y, y B/Y males.
↵b N, number of progeny scored.
↵c N/no. of ♀♀.
↵d % NDJ = 100 × 2 × (B⁺ females + y B males)/(N + B⁺ females + y B males).
↵e Map length of pn-y⁺ interval expressed in centimorgans.
↵f Recombination frequency in the cn-bw interval on chromosome 2 measured in progeny of cn bw/+ females crossed with cn bw males.
↵g Recombination frequency in the st-e interval of chromosome 3 measured in progeny of Z3i, st/Df(3R)T16, e females or mod(mdg4)^T6 e/Df(3R)GC14, st females crossed with st e males.
↵h GC14 = Df(3R)GC14.
↵i Df(3R)T16 was used instead of Df(3R)GC14 in the third chromosome recombination crosses.
