Summary
From the measurement of end-point dilution of stigma extracts of B. oleracea tested against S-protein antisera it was found that stigmas homozygous for a particular S-allele contained more specific S-protein than those heterozygous for the same S-allele. There was generally twice as much S-protein in the homozygote as in the heterozygote.
