Whole-genome sequencing reveals asymmetric introgression between two sister species of cold-resistant leaf beetles

Svitlana Lukicheva & Patrick Mardulyn
A large number of genetic variation studies have identified cases of mitochondrial genome introgression in animals, indicating that reproductive barriers among closely related species are often permeable. Because of its sheer size, the impact of hybridization on the evolution of the nuclear genome is more difficult to apprehend. Only a few studies have explored it recently thanks to recent progresses in DNA sequencing and genome assembly. Here, we analysed whole-genome sequence variation among multiple individuals...
