Outcross is the opposite of inbreeding. This means a mating between two cats of the same breed, but from different bloodlines.
The German Rex is a very small breed that lacks different bloodlines. About 15 years ago the breed was nearly extinct; with only a few cats the breed was revived.
For the German Rex outcrossing means mating to an unrelated straightcoated cat.
The German Rex originates from a coatmutation in a domestic shorthair from Berlin.
Just like all other rexbreeds, the breed was created from this single ancestress; this cat and her offspring needed to be outcrossed over and over to unrelated straightcoated cats to build up a healthy population.
The ideal outcross-mate for the German Rex is a domestic or European shorthair, the type of these cats are most similar to the type of the German Rex.
A kitten from an outcross mating between a curly German Rex and an unrelated straightcoated cat will always be straightcoated. These cats are called hybrids. A hybrid mated to a curly German Rex will give 50% curly offspring.
