"Heterosis" Meaning

Heterosis refers to the phenomenon where the offspring of two different purebred parents exhibit increased vigor, strength, or fitness compared to one or both of the parent lines. This is often seen in crop breeding and animal husbandry, where crossing different varieties or breeds of plants or animals can result in improved traits such as higher yields, disease resistance, or tolerance to environmental stresses.
