But with at least three graphically captive populations ( USA,
Australia/NZ and Europe) it may be possible to transfer genetic material
from one group to another. To be successful it may have to be controlled
in some way or another.

For you genetic experts, would it be possible to breed a "cross"
with a pure strain, through a number of generations, so that all the
offspring are pure?
