Clustering of genes with related functions on the same chromosome reflects the fact that many genes arose through the process of duplication of a single gene, followed by divergence.

Question

Quizplus · Accepted Answer

Clustering of genes with related functions on the same chromosome is a result of the process of gene duplication and divergence. When a single gene duplicates, the duplicate gene may retain the original function, or it may acquire a new function through mutations. Over time, these duplicated genes diverge in function and structure, but many of them retain some level of similarity and may continue to contribute to related biological processes. As a result, genes with related functions tend to be located near each other on chromosomes, reflecting their shared evolutionary history.
