Although hybridization is generally considered to be symmetrical, with both hybridizing species being equally likely to be the male or female parent, several studies have demonstrated the presence of asymmetrical hybridization and introgression from one species to the other. We investigated the direction of natural hybridization between two sympatric forest tree species in North America (<em>Populus deltoides<\/em> Bartr. ex Marsh. and <em>Populus balsamifera<\/em> L.) using species-specific single nucleotide polymorphism (SNP) markers in both the nuclear and chloroplast genomes. All natural hybrid individuals, identified from morphological traits, had nuclear alleles corresponding to both parental species, while the chloroplast genotypes showed similarity to <em>P. deltoides<\/em>, indicating asymmetrical hybridization with <em>P.<\/em> <em>deltoides<\/em> as the maternal and <em>P. balsamifera<\/em> as the patternal donor species. This observed asymmetrical hybridization may be attributable to cytonuclear interactions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Published in Canadian Journal of Botany 85(12): 1227-1232 Natural hybridization has long been recognized as a means for gene flow between species and has important evolutionary consequences.
