Abstract

Pseudogenes are those regions in the genome that have sequence similarity to functional genes but have decayed and do not have obvious functions. It is estimated that the human genome contain more than 10 000 easily recognizable pseudogenes and many more fragmented sequences, mainly arose through one of the following three mechanisms: duplication, retrotranposition and spontaneous loss of function.

  • pseudogene;
  • human genome;
  • retrotransposition;
  • evolution;
  • comparative genomics
