Fremdvervielfältigung
Fremdvervielfältigung, also known as heterosis or hybrid vigor, is a phenomenon in biology where the offspring of two different species or varieties exhibit greater vigor, productivity, or other desirable traits than either of the parents. This concept was first described by the German botanist Carl Correns in the early 20th century. The term "Fremdvervielfältigung" translates to "foreign multiplication" in English, reflecting the idea that the offspring are produced through the combination of different genetic material.
Heterosis is often observed in plants and animals, and it can be attributed to several factors, including
In animal breeding, heterosis can also be observed, particularly in livestock. For example, the crossbreeding of
Despite its potential advantages, heterosis also has its limitations. The hybrid vigor is often not stable
In summary, Fremdvervielfältigung, or heterosis, is a biological phenomenon where the offspring of two different species
