If a gene sequence in one organism is highly similar to the sequence of another gene in another organism it is called

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

Explanation:

Homology refers to the fact in which the sequences of two or more proteins or nucleic acids are very similar due to the fact that they have the same evolutionary origin. 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.
