Which statement is true?

Question

Quizplus · Accepted Answer

Orthologs are genes in different species that evolved from a common ancestral gene through speciation. Therefore, all orthologs are homologs as they share a common ancestor. However, not all homologs are orthologs as some may have arisen through gene duplication events within a species, becoming paralogs. Therefore, option A and B are incorrect. Option C is incorrect because not all homologs are orthologs, as explained above. Option E is incorrect because it contradicts option D.
