![]() ![]() The term homology refers to the state of sharing a common evolutionary origin. One often quantifies the percent identity between two sequences. ![]() We might use the term identity to refere more exact situations, such the state of possessing the same subsequence. Before we get into how this is done, we must also consider that there are many types of evolutionary relationships among sequences.įirst, there is similarity, which fits the intuitive meaning of the degree of resemblance between two sequences. By comparing two sequences, we can determine whether two sequences have a common evolutionary origin if their similarity is unlikely to be due to chance. ![]() Biological sequences evolve through a process of mutation and natural selection. ![]()
