Population genetics of the moss Plagiothecium undulatum (Hedw.) Schimp. I. Inheritance of allozymes

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 deri...

Zusammenfassung:	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 Icd in P. undulatum are discussed.
