Abstract

In bryophytes and other organisms with a dominant haploid generation the actual hybrid is the diploid sporophyte which holds both parental genomes. A single inter-species fertilization event leads to several thousand meiotic events, each resulting in four haploid spores. These spores recombines the parental genomes and we know from earlier studies that the small minority of spores that are actually viable have a quite skew representation of the parental genomes, i.e. a form of immediate introgression. We will commit detailed molecular studies of the genomic consequences of such hybridization events.
