Genotype and individual data for genetic structure in Louisiana Iris species reveals patterns of recent and historical admixture

Alexander Zalmat, Alex Sotola, Chris Nice & Noland Martin
Premise: When divergent lineages come into secondary contact reproductive isolation may be incomplete, thus providing an opportunity to investigate how speciation is manifested in the genome. The Louisiana Irises (Iris, series Hexagonae) comprise a group of three or more ecologically and reproductively divergent lineages that can produce hybrids where they come into contact. In this study we sought to estimate standing genetic variation to understand the current distribution of population structure in the Louisiana Irises....
