Since n + m is less than nm + \ this type of reduplication is of the 

 nature of a repulsion. 



The EBL group of experiments conducted by Bateson and Punnett 

 and described in Proc. Roi/. Soc. B, Vol. 84, p. 7, illustrates this case. 

 The cross Ebl x eBL shews repulsion between E and B and coupling 

 between B and L. It will simplify comparison to write the factors in 

 the order BLE. It has been found that 



BL : 81 : bL : bl :: 7 : 1 : 1 : 7, 

 and BE : Be : bE : be :: 1 : m : m : 1. 



Hence it may be deduced that 



LE : Le : IE ; le :: 7 + m : 7m 4- 1 ; 7m + 1:7 + m, 



which indicates a repulsion. This appears to have been observed, but 

 it is not clear to me from the description of the results whether the.se 

 three types of reduplication have been observed in the same cross. 

 They should certainly be looked for.
