Genetic drift—the random fluctuation of allele frequencies from one generation to the next—exerts its strongest effects in small populations. In a small population, chance events can cause the loss of beneficial alleles or the fixation of harmful ones, reducing adaptive potential and increasing the risk of extinction. The magnitude of drift can be mitigated by maximizing the effective population size, a key goal of genetic management strategies implemented by zoo conservation programs.
: Usually follows an autosomal recessive pattern, meaning an animal must inherit two copies of the mutated gene (one from each parent) to be albino. : Usually follows an autosomal recessive pattern, meaning
: Zoos aim to retain the maximum amount of "founder" genetic diversity to ensure populations remain resilient against diseases and environmental changes. Mean Kinship & Pedigree Management : Tools like Species Survival Plans (SSPs) : Usually follows an autosomal recessive pattern, meaning
