Genetic consequences of outcrossing in the cleistogamous annual, Impatiens capensis. II. Outcrossing rates and genotypic correlations

Abstract

Examined the electrophoretic genotypes of seeds derived from cleistogamous and chasmogamous (CH) flowers in 6 populations of the facultatively cleistogamous annual, Impatiens capensis. Multilocus estimates of the outcrossing rates for the strongly protandrous CH flowers ranged from 0.29-0.71 and were higher than estimates based on single-locus data. Such results suggest that the CH flowers experience variable levels of both geitonogamous self-fertilization and biparental inbreeding. -from Authors
