Hybrid vigor, also known as heterosis, is a term used to describe the superior qualities of offspring resulting from the cross-breeding of genetically diverse individuals. Synonyms for hybrid vigor include increased adaptability, heterozygosity, enhanced fitness, hybrid vigor effect, outbreeding enhancement, and genetic heterogeneity. The phenomenon of hybrid vigor is observed in various fields such as agriculture, animal breeding, and human biology. Farmers and breeders intentionally mate two different species to produce crops or animals that have higher yields, resistance to diseases, and better growth rate. Similarly, humans with mixed ancestry often have a healthier immune system and better physical abilities, showcasing hybrid vigor in the human population.
