Genetic Load in Plant Populations

Genetic load refers to the presence of deleterious alleles within a population, reducing its overall fitness. In plant populations, genetic load can accumulate due to inbreeding, genetic drift, or bottleneck events. While some level of genetic load is typical, high levels can lead to decreased fertility, stunted growth, and increased susceptibility to diseases. Breeding programs aim to manage genetic load by introducing genetic diversity, often through hybridization or outcrossing. Understanding genetic load is essential in conservation genetics and agriculture to ensure resilient plant populations with high adaptability and productivity.
