Effects of P and M in presence of L. 



For simplification of tabulation the white-eyed forms are here 

 grouped together. The full records, however, show that the expected 

 forms are represented and in due proportion, whether as LP and P only, 

 when the R factor is absent; as PTf and RP only, when the R factor 

 is present in the condition of purity, or as all four forms when the R 

 factor is present but in the impure condition. 



(a) The \- factor pure, LL. 



If we assume the L factor to be merely an intensifier, its presence 

 in the pure condition will be indicated by a series corresponding to the 

 last but by a series in which the RB and PP forms are replaced by an 

 R «', P2, or R,), and the PPG and PP, forms by the CPG or GPP 

 form.

The deficiency in the number of whites and purples is large and is 

 associated with an excess in the number of reds. There is here, also, 

 a further complication which arises from the confusion which we have 

 shown to arise in certain cases between the Og and GPG forms (see 

 under the description of the GPG form above). If we take only those 

 families in which such confusion cannot arise, those, that is, in which 

 the PPMM form is Ri or Gi, we obtain the following figures :
