The Genes of a Gene Family That Consist of Two

Question

The genes of a gene family that consist of two or more homologous genes are called ________.
A) Orthologs
B) Paralogs
C) Polylogs
D) Homologs

Accepted Answer

Homologs refer to any genes that share a common ancestor, while paralogs specifically refer to genes within a single organism that have diverged from a common ancestor. Orthologs refer to genes that have diverged due to speciation events, and polylogs is not a recognized term in genetics. Therefore, the answer is B) Paralogs.
