Heterosis

Heterosis, or hybrid vigor, occurs when two different parent plants or animals are crossed, producing offspring that are stronger, healthier, or more productive than either parent. This happens because the new combination of genes can enhance traits like growth rate, disease resistance, or adaptability. Essentially, heterosis leverages genetic diversity to create offspring with improved characteristics, which is why hybrid crops and hybrid animals often outperform their purebred counterparts. It's a natural way to improve quality and performance in agriculture and breeding programs.
