The result is that the colour intensity of the normal offspring ex the cross 
plain x quail depends upon the marking intensity of the quail parent. It 
follows that the normal subtypes 1, 2, 3 and 4 may be represented as pQ 1 , pQ~, 
PQ 3 and pq 4 respectively. It must be noted that the "eye-spots" of the normal 
subtypes are, as a rule, a little lighter than those of the corresponding quail 
subtypes, owing to the "palliating" function of P. This factor acts, as 
mentioned in Chapter U, as a suppressor of the irregular lines and dots 
characteristic to the Q, pattern, ami may at the same time tend to diminish 
the intensity of the "eye-spots" though in a slight degree.

As already stated (Chapter V), P and Q, are quite independently distributed 
in the gametogenesis, and we should expect the presence of light normal 
(PQ,') in the above family (A 4Öo'i5) in which a number of light quails (pQ 1 ) 
appeared. Contrary to expectation, no individuals of light normal type ap- 
peared in this case. This can not be interpreted otherwise than by the as- 
sumption that the individuals with the genetic constitution PQ, 1 (light normal) 
really occurred, but that the "eye-spots" were palliated by the P factor to so 
extreme a degree as to make them indistinguishable from pure plain. Quite 
similar case is met with in A454'i5 A46d'i5 A 463'i5 (p. 134), A536'i5
