Hum Hered. 1978;28(4):280-4. doi: 10.1159/000152968.


The results of Pi typing on 280 Bretons from Morbihan (Southern Brittany) are reported. 6 phenotypes and 5 alleles have been found in this study. Pi M is the most frequent as in other populations. Pi S and Pi F apears as the two main variants in population genetics.
