The Savannah (A) is a hybrid domestic cat breed. It is the result of selectively breeding domestic cats with African servals (B) in order to produce the signature color markings and large size.
Not all, but many of these Savannah cats are able to successfully reproduce with other domestic cats.
What could be a long-term effect of this type of artificial selection by humans?
for example: Dog breeding is another prime example of artificial selection. Although all dogs are descendants of the wolf, the use of artificial selection has allowed humans to drastically alter the appearance of dogs.
