This is a well-known principle in genetics, which makes crossbred animals superior to their purebred parents, both in performance and in robustness. This heterosis effect is particularly important for low heritability traits such as fertility, prolificacy, dairy qualities or semen quality.

This effect is only effective in the first cross, it is not transmitted to the following generations. This is why it is imperative to respect the genetic scheme.
