  • n. A defective segment of DNA that resembles a gene but cannot be transcribed.

  • n. A segment of DNA that is part of the genome of an organism, and which is similar to a gene but does not code for a gene product.


Sorry, no etymologies found.


  • Isolation and nucleotide sequence analysis of the beta-type globin pseudogene from human, gorilla and chimpanzee.

    Behe, Common Descent, & UD

  • A bit further down in the human pseudogene is a deletion mutation, where one particular letter is missing.

    Behe, Common Descent, & UD

  • For example, there's what's termed a pseudogene copy of one of the BRCA genes, which has inactivating mutations in it, and no longer produces any protein.

    Ars Technica

  • Usually, that's it, and that copy becomes a so-called pseudogene, functionless litter, part of the famous junk DNA.


  • In the region between the two gamma genes and a gene that works after birth, human DNA contains a broken gene (called a "pseudogene") that closely resembles a working gene for a beta chain, but has features in its sequence that preclude it from coding successfully for a protein.

    Behe, Common Descent, & UD

  • Thus finding a pseudogene in both chimps and humans that has exactly the same mutations in the same places was compelling evidence for him of common ancestry.

    A Disclaimer for Behe?

  • In "The Design of Life" they presented a case in which humans and guinea pigs share the same mistake. (page 133) the GULO pseudogene.

    A Disclaimer for Behe?

  • It doesn't make sense to design a pseudogene (a gene that no longer functions as a gene) once, let alone twice — once in chimpanzees and once in humans.

    Behe, Common Descent, & UD

  • That strong evidence from the pseudogene points well beyond the ancestry of humans.

    Behe, Common Descent, & UD

  • The beginning of the human pseudogene has two particular changes in two nucleotide letters that seems to deactivate the gene.

    Behe, Common Descent, & UD
