The twoheavy lines give the upper and lower limiting values for thesuccessive mean inbreeding coefficients. The true value ofthe curve lies somewhere in the ruled area between theseheavy lines. For comparison the curves for continued broth-er X sister (B X S), parent X oflfspring (P X O), and firstcousin X first cousin breeding are included. O X C denotessingle cousin matings, and C X C^ double cousin matings. 12 MAINE AGRICULTURAL EXPERIMENT STATION. CO£rr/C/£NT3. Fig. 2.
