Values of the Successive Coefficients of Inbreeding 

 in the Case of Continued Cousin Mating 



100. The rate of approach is different, however, 

 in the different cases. The curves fall into two 

 pairs. The brother x sister and the double cousin 

 curves are precisely alike so far as concerns their 

 curvature or shape at any given point. Similarly, 

 the parent X offspring and single cousin curves 

 are of the same shape. The essential 'point of 

 difference is thai the cousin curves lag a generation 

 behind the others.
