Question

Quizplus · Accepted Answer

Species fusion occurs when two populations, previously separated and potentially beginning to diverge, come back into contact and interbreed to such an extent that they effectively merge into a single population again. This can happen if the differences that developed during their separation are not significant enough to prevent interbreeding.
