The origin of a new diploid species by means hybridization requires the successful merger differentiated parental species' genomes. To study this process, genomic composition three experimentally synthesized hybrid lineages was compared with that an ancient species. and hybrids concordant (rs = 0.68, P < 0.0001), indicating selection to large extent governs formation. Further, nonrandom rates introgression significant associations among unlinked markers in each imply interactions between coadapted genes constrain
