19. Mutation Rates and Genetic Diversity
Within the Chernobyl dog population, mutation rates are notably higher due to the persistent exposure to radiation. This environmental factor accelerates genetic changes, resulting in a diverse gene pool. While some mutations are neutral or detrimental, a few may offer advantages, contributing to the dogs’ survival in the exclusion zone. The increased genetic diversity within this population is a double-edged sword; it provides a broader range of traits for natural selection to act upon but also poses risks of deleterious genetic anomalies. This balance is crucial for understanding how these dogs continue to adapt and thrive in a challenging environment.
