The results of Pi typing 5237 unrelated Caucasians are presented, together with the phenotypes of 2203 children from 1156 families. The estimate of the gene frequencies in the United Kingdom are Pi-M equal 0-9303, Pi-S equal 0-050, Pi-Z equal 0-0141, Pi-minus equal 0-0015, Pi-V equal 0-0004. Evidence for three new alleles, Pi-W2, Pi-Y2 is presented. The results of twin studies and quantitative studies are discussed.
本文展示了对5237名无亲缘关系的白种人进行Pi分型的结果，以及来自1156个家庭的2203名儿童的表型。英国基因频率的估计值为：Pi-M等于0 - 9303，Pi-S等于0 - 050，Pi-Z等于0 - 0141，Pi-minus等于0 - 0015，Pi-V等于0 - 0004。文中还展示了三个新等位基因Pi-W2、Pi-Y2的证据。同时讨论了双胞胎研究和定量研究的结果。
