How are multigene families formed?
How are multigene families formed? Multigene families are formed through a variety of evolutionary events that generate gene paralogs (i.e., duplicate nonhomologous gene copies). Such events may include a single gene amplification event or series of sequential duplications involving individual genes or entire genomes. What is a multigene family composed of? A multigene family is a group of genes that have descended from a common ancestral gene and therefore have similar functions and similar DNA sequences. A group of related multigene families is sometimes called a supergene family. What genes are located in multigene families? Multigene families are believed to...
