Evidence of extensive mitochondrial introgression with nearly complete substitution of the typical Squalius pyrenaicus ‐like mtDNA of the Squalius alburnoides complex (Cyprinidae) in an independent Iberian drainage

Abstract

The first occurrence of massive mitochondrial introgression of Squalius aradensis genes in Squalius alburnoides , a hybridogenetic complex that usually carries mtDNA of its maternal ancestor ( Squalius pyrenaicus ) is reported. Possible implications of such introgressions for the history of the complex are discussed.
