Genetic hybridization

Genetic hybridization is the process of interbreeding individuals from genetically distinct populations to produce a hybrid. A genetic hybrid would therefore carry two different alleles of the same gene.

    The pygmy hog (Porcula salvania), now highly endangered and restricted in a small region at the southern foothills of the Himalaya, is the only suid species in mainland Eurasia that outlived the expansion of wild boar (Sus scrofa). Here, the authors analyze genomes of pygmy hog and related suid species, and identify signals of introgression among these species.

    Analysis of genomes from bonobo and chimpanzee populations reveals an ancient admixture event between bonobos and an extinct great ape several hundred thousand years ago and suggests introgression of functional genes from the archaic ape into bonobos.

    Analysis of crow admixed genomes in a European hybrid zone shows that variation in hybrid colour phenotypes is explained by recessive epistasis between two pigmentation genes, which are targets of divergent selection.

    Hybridization can contribute to diversity from the genomic to the species level. Here, Eberlein, Hénault et al. investigate genomic, transcriptomic and phenotypic variation among wild lineages of the yeast Saccharomyces paradoxus and suggest that an incipient species has formed by recurrent hybridization.

    Stocking of hatchery produced fish is widely used to supplement wild fish populations. Here, the authors show that supplementary stocking can unintentionally favour introgressed individuals with domestic genotypes and compromise the fitness of a wild population of Atlantic salmon.
