Genealogical Analysis of Replicate Flower Colour Hybrid Zones in Antirrhinum.

ABSTRACT: A major goal of speciation research is identifying loci that underpin barriers to gene flow. Population genomics takes a 'bottom-up' approach, scanning the genome for molecular signatures of processes that drive or maintain divergence. However, interpreting the 'genomic landscape' of speciation is complicated, because genome scans conflate multiple processes, most of which are not informative about gene flow. However, studying replicated population contrasts, including multiple incidences of secondary contact, can strengthen inferences. In this paper, we use linked-read sequencing (haplotagging), F_ST scans and genealogical methods to characterise the genomic landscape associated with replicate hybrid zone formation. We studied two flower colour varieties of the common snapdragon
