Unformatted text preview: genes through duplication, forming multigene families. Key Concept 4: Gene duplication can occur through whole genome duplication, duplication of chromosomal segments, or duplication of individual genes. Key Concept 5: Repeated duplication can produce large, tandem arrays of individual genes, which is beneficial when a lot of RNA needs to be made quickly. Key Concept 6: The structure of whole genomes can evolve through exchange of chromosomal segments by translocation, duplication of chromosomal segments, or deletions of chromosomal segments....
