When quail is crossed with the striped-quail heterozygous for S, the 
results are exactly similar to those given above, no ordinary striped being 
produced. It is, therefore, evident that pale-quail and quail are equally 
destitute of the factor necessary for turning the striped-quail into the ordinary 
striped.

On the other hand, crosses of plain with heterozygous striped-quail 
produced the ordinary striped and normal instead of striped-quail and quails. 
Similar results are obtained by crossing normal and striped-quail. It is 
obvious that plain and normal have a common factor, the introduction of 
which turns striped-quail into ordinary striped ; this factor is undoubtedly P.
