Different strains are selected by selecting parents with like characteristics - no such selection takes place in wild things. Even selected strains have a lot of variation within the strain. One example for which I have much first hand knowledge is the size of eye of lean in a hog carcass. With pure strains it varies a great deal - with crossbred hogs much less. The interesting thing is people were making the same arguments 50 years ago - now isolated strains are a thing of the past in animal science. except to produce the crossbreds.
