 16 lies in the fact that a standard bred and supposedly pure bred family should carry factors 

 normal to other breeds, and without being suspected. (Fig. 16.) 



On the basis of her offspring when 

 mated with a splashed AndaUisian male 

 the formula of White Wyandotte 2031 

 must be, with regard to the same char-

Because this individual does not carry 

 P she is white and neither (Re), (rE), 

 nor B can find expression. However, 

 when mated with a splashed Andalusian 

 the theoretical result is as follows : 



Photographs of the four kinds of in-
