Quizplus · Accepted Answer

The point at which two gene copies are descended from the same ancestral gene copy is called the coalescent point. This term is commonly used in population genetics to describe the point in time where the lineages of two genes converge and merge into a common ancestor. This point is also known as the most recent common ancestor (MRCA) for the two gene copies.
