Population genetics of the moss plagiothecium undu/atum (Hedw.) schimp. i. inheritance of allozymes

Abstract

Twenty-one allozyme loci were assayed in a subpopulation of the dioecious moss Plagiothecium undulatum. Six loci were polymorphic and could be used to demonstrate the different expression of allozymes at the haploid gametophytic and diploid sporophytic life stage. Progeny analysis on sporelings derived from heterozygous sporophytes revealed that for Gpi-2, Pgm-1 and Icd-1 the maternal and paternal genotypes segregated in a simple 1:1 ratio. The possibilities of gene duplications for Pgm and led in P. undulatum are discussed. © 1991 The Genetical Society of Great Britain.
