Haldane’s model

Haldane's model, named after the scientist J. B. S. Haldane, is a theoretical framework in evolutionary biology that explains how genetic variations can spread through a population. It emphasizes the idea of genetic drift and selection in small populations, where random changes can have a large impact on genetic makeup. Haldane introduced concepts about how quickly beneficial traits can become common and how certain traits can become fixed or lost over generations. His work helped illuminate the processes driving evolution, underscoring the balance between chance and natural selection in shaping species.
