The results of the above experiments, are explicable only on the as- 
sumption that the factorial constitution of striped-quail and striped is re- 
spectively SpQ, and SPQ. 
Quite similar results were obtained with regard to the moricaud and 
moricaud-quail markings. F 1 animals produced by the cross of moricaud 
and quail show no significant difference from the homozygous moricaud ; they 
were inbred as well as cross-bred with recessives with the following results. 
F, moricauds inbred.
