  1. 1.

    Formulae are given for the probable errors of linkage and reduplication values calculated from the offspring of crosses of typesAB. ab ×abab, Ab.aB ×abab,AB.ab ×AB.ab, andAb.aB ×Ab. aB.

  2. 2.

    A method is given by which the best possible linkage values may be calculated from the offspring of the latter two crosses, i.e. fromF2.

  3. 3.

    If this method is employed,F2 is almost as accurate a means of measuring linkage as are the offspring fromF1 × double recessive; it is also slightly more sensitive as a means for the detection of linkage.
