Genetic biodiversity decreases through selective breeding, captive breeding, genetic bottlenecks, and the founder effect, all of which reduce the available gene pool.
يقلل التنوع الجيني عن طريق الانتقاء الاصطناعي، والتكاثر في الأسر، والاختناقات الوراثية، وتأثير المؤسسين، حيث تحد هذه العمليات من تجمع الجينات المتاحة.
