If we regard the gene P—CRR', p—CRr' as already discussed, P' may 
also be regarded as a complex of genes CRR' but p' must differ from p, 
inasmuch as in the paleas, purple and non purple are allelomorphic, but no 
red ever occurs, whereas in the awn, purple and red are allelomorphic to each 
other. It can be imagined that in p', err' behave as a single unit, allelomorphic 
to the complex CRR'. Else P' and p' may differ only in C but contain R 
and R' providing that cRR' forms no anthocyanin.
