In this case, if we consider the parent egg, G in the third series, as 

 the N of the first generation of the fourth series, both results come in 

 a single form which may be represented as below : 



A = G in the third and N in the fourth series ; 

 B = N in the third and S in the fourth series.

If we compare the results obtained by the first and the second 

 series of experiments, we can easily see that they behaved in inheritance 

 in a similar manner to those above described, certain inconsistent 

 results being due perhaps to the appearance of divoltine white eggs 

 which prevented the elimination of the antagonistic characteristics 

 during one generation.
