The population genetics of the selfincompatibility polymorphism in papa ver rhoeas. II. the number and frequency of S-alleles in a natural population (R106)

Abstract

A randomly-drawn sample of 51 plants from a natural population (R106) carried between them 31 different S-alleles whose frequencies were, contrary to theoretical expectation, significantly unequal. Two alternative hypotheses are proposed to account for this unexpected observation. One of the eleven S3 alleles found in the experiment appeared to be a stigma part mutant of the revertant type. © 1981 The Genetical Society of Great Britain.
