Multigenerational hybridisation results in heterosis and facilitates adaptive introgression, with no evidence of outbreeding depression in a pair of marine gastropods.

ABSTRACT: Anthropogenic environmental changes continue to threaten species globally. For example, translocation of species has caused unintentional hybridisation, which has contributed to species declines. On the other hand, hybridisation can be used to increase the evolutionary potential of species vulnerable to rapid environmental change, although the benefits of mixing genetically divergent lineages do not come without risks to individual fitness and the long-term viability of populations. Here, we use a combination of genome-wide Single Nucleotide Polymorphism (SNP) markers, mitochondrial DNA sequencing and measurements of growth rate to determine the genetic consequences of hybridisation between two congeneric marine gastropods across 27 years (~18 generations).
