Quizplus · Accepted Answer

Orthologs are genes that originated from a common ancestor through speciation events and are found in different species. In this case, the two species of beetles carry a single copy of a gene that codes for an enzyme that has started to diverge, hence they are orthologs. Paralogs, on the other hand, are genes that originated from a gene duplication event within a species, while reticulations refer to the exchange of genetic material between different lineages. Not homologs and analogs are synonymous terms that refer to genes that have similar functions but are unrelated in sequence or origin.
