  • 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.
