The Role of Genetic Drift in Accelerating Genetic Erosion in Small Populations

Explore the crucial role of genetic drift in accelerating genetic erosion within small populations in our latest documentary, "Genetic Drift: The Silent Threat to Biodiversity." Discover how chance events drastically alter allele frequencies, leading to reduced genetic diversity and increased extinction risk—especially in endangered species and cultivated crops. This video delves into the mechanisms of genetic drift, real-world examples like the Florida panther and Tasmanian devil, and the dire implications of genetic erosion on biodiversity and adaptability. Join us as we uncover the need for conservation strategies to safeguard our planet's genetic heritage.
