Hybrid vigor)
- Heterotic string theory is a field of physics.
Heterosis is increased strength of different characteristics in hybrids; the possibility to obtain a "better" individual by combining the virtues of its parents.
This is commonly known as hybrid vigor. It is an observable phenomenon in which a hybrid plant or animal may exhibit greater strength, health or faster rate of growth than its parents. The term often causes controversy, particularly in terms of domestic animals, because it is sometimes believed that all crossbred plants or animals are better than their parents; this is untrue. Rather, when a hybrid is seen to be superior to its parents, this is known as hybrid vigor. Heterosis is an example of heterozygous advantage.
