Pseudogene
An inactive gene derived from an ancestral active gene. Pseudogenes are often recognized by nonsense or frameshift mutations that disrupt an open reading frame that encodes a functional protein in a related genome.

PSEUDOGENE - Inactive but stable components of the genome which derived by duplication and mutation of an ancestral, active gene. Pseudogenes can serve as the donor sequence in gene conversion events.

Pseudogenes are designated with the Greek letter psi, e.g., ΨHBBP1 is a nonfunctional version of the gene encoding the beta chain of human hemoglobin. The human genome contains some 15,000 pseudogenes.

All of these genes have similar amino acid sequences due to their evolution from the same ancestral gene.
Some families of genes contain hundreds of genes.

The genome of eukaryotes is loaded with 'dead genes' called pseudogenes. Pseudogenes are copies of working genes that have been inactivated by mutation. Most pseudogenes do not produce full proteins. They may be transcribed, but not translated.

And so we sequenced a whole bunch of these pseudogenes of individual humans and great apes, and sure enough we found that the human pseudo gene had many, many more mutations.

Some non-coding DNA represents pseudogenes that can be used as raw material for the creation of new genes with new functions.

Further evidence for common descent comes from genetic detritus such as pseudogenes, regions of DNA which are orthologous to a gene in a related organism, but are no longer active and appear to be undergoing a steady process of degeneration[6].

DNA contains 3 sequences also present in plastid DNA: 12 kb and 1 kb fragments from the inverted repeat region and the ribulose bisphosphate carboxylase large subunit coding sequence. The sequences in mitochondrial DNA appear to be pseudogenes.
