Suppose Researchers Know That Two Species of Fish Began Diverging

Short Answer

Suppose researchers know that two species of fish began diverging from a common ancestor when they were separated by the formation of the Isthmus of Panama 6 million years ago.The genetic divergence between these two species at the hypothetical HYR gene is 3 percent.The ZTG1 gene evolves twice as fast as the HYR gene.Assuming a molecular clock, you would expect a _______ percent genetic divergence at ZTG1 between two species of fish that diverged a million years ago.
