Pseudogene

Definition(s)

A copy of a gene that usually lacks introns and other essential DNA sequences necessary for function. Pseudogenes, though genetically similar to the original functional gene, are not expressed and often contain numerous mutations.

A pseudogene is a DNA sequence that resembles a gene but has been mutated into an inactive form over the course of evolution. A pseudogene shares an evolutionary history with a functional gene and can provide insight into their shared ancestry.
