Fig. 24-1 Graphic Representation of the Calculations in 

 Table 24-2. The abscissae represent varying distances of an allele 

 A/a from its centromere, the ordinates represent the ratios I + II 



I+II + III 



each curve plots the values of this ratio for the indicated distance 

 of B/b against various distances of the A/a locus from its centromere
