Homologous genes are closely related genes found in different species that share a common ancestry, playing a role in the evolution of proteins.
Homologous genes are closely related genes found in different species that share a common ancestry. They can be identified by comparing protein or DNA sequences, where high similarity indicates a shared origin.
For example, the hemoglobin gene of humans and the myoglobin gene of chimpanzees are considered paralogs, which are a type of homologous genes that have diverged after duplication.
Homologous genes play an essential role in the evolution of proteins and can help trace evolutionary relationships between different species.
