Would fruit flies be reproductivley isolated if two different populations of them were enclosed, but connected?
by a single tube. So again, they are in two enclosed areas but connected by one tube.Are they considered “reproductively isolated”?
They are reproductively isolated from the other fruit flies in the world BUT if the tube is big enough for them to move through, then the two groups are not reproductively isolated from each other.
