pseudogenea nucleotide sequence, similar to that of a known functional gene, but that is inactive due to the accumulation of MUTATIONS. A pseudogene may result from a tandem DUPLICATION of an existing gene or REVERSE TRANSCRIPTION of the transcript of the gene (so that it lacks the introns and has a POLY(A) TAIL).
