The work analyzes the canine population that lives next to the nuclear power plant and compares it with that of the city of Chernobyl, located about 16 kilometers
Chornobyl dog population shows genetic signatures of directional selection
The latest research on the wild population of dogs in Chornobyl reveals that the genetic differences between these dogs and other similarly isolated dog populations are likely evidence of directional selection, not mutation. The work suggests a potential association between genetic selection and environmental variables and could advance understanding of local adaptation and genomic resilience in contaminated environments. The study appears in Genes.
Although the landscape around the Chernobyl nuclear power plant may seem like it's been destroyed by the apocalypse, packs of dogs have managed to populate it. Scientists have now described how the animals managed to do it and how it's reflected in their genes.
