近三分之一的可能组合之间的28个S等位基因从骨髓干和千头羽衣甘蓝（甘蓝。acephala）的显性关系进行了测定。在5个等位基因杂合体中，花粉和柱头的独立作用比显性作用多，但花粉的显性作用比柱头的显性作用多。花粉中显性的相对频率和非线性显性的发生频率以及柱头中的非线性显性的发生频率与Sampson的5位点基因互作假说的预期一致。[参见XXXI，1332]。
Dominance relationships were determined for nearly a third of the possible combinations between 28 S alleles from marrow-stem and thousand-head kales (Brassica oleraceavar.acephala). In pollen and stigma independent action is more common than dominance in 5 allele heterozygotes, but dominance occurs more frequently in pollen than in the stigma. The relative frequency of dominance and the occurrence of nonlinear dominance in the pollen and more frequently in the stigma are in accordance with expectation based on Sampson's hypothesis of gene interaction at the 5 locus. [Cf. XXXI, 1332].
