mario62 [17]

Answer:

This question lacks options, options are: a.related. b. homologous. c protein-coding, d. comparative. The correct answer is b.

Normally two sequences have a high similarity because they are homologous, that is, they share a common ancestor. If two sequences in an alignment are from a common ancestor, mismatches can be interpreted as point mutations (substitutions), and gaps as insertion or deletion mutations introduced into one or both lineages in the time since they diverged.
