Question

Quizplus · Accepted Answer

Homologous genes encoding globins in the human genome are derived from a single ancestor that duplicated 500-600 million years ago, indicating that these genes belong to a gene family. Gene families are groups of genes that share a common ancestor and have diversified in structure and function through gene duplication and evolutionary divergence.
