Conservation genetics programs that maintain genetic diversity in small wildlife populations have direct welfare implications through inbreeding depression and disease susceptibility.
Conservation genetics intersects with welfare in profound ways. Inbreeding depression is not just a population-level risk — it manifests as individual welfare costs: reduced immune function meaning more disease, reproductive failure causing distress, and developmental abnormalities causing physical limitation. Genetic rescue — introducing individuals from genetically distinct populations — produces dramatic welfare improvements at individual and population levels simultaneously. The Florida panther genetic rescue case is paradigmatic: translocating eight Texas pumas reversed the population's decline and eliminated the severe developmental defects (kinked tails, cardiac abnormalities) that had plagued the inbred Florida population. Conservation genetics is welfare science operating at population scale.
