Sometimes you will find that the offspring of two animals are larger and healthier than their parents. The reason behind this is called ‘hybrid vigour’, also known as ‘heterosis’.
Basically, it’s when the offspring are seen to be ‘superior’ to their parents. If the opposite happens and the hybrid inherits traits from their parents that makes them unfit to survive, the result is referred to as outbreeding depression.

Here’s one example of hybrid vigour…

Gracie (55g) X Kipp (90g) = Delu (120g)!

Just so you can see the size difference between mother and daughter..

That’s one hell of a big difference in one generation!
