Shown are summaries for the interspersed repeats that were identified using RepeatMasker( http://ftp.genome.washington.edu/index.html ) for the analyzed sequences. The average values for human autosomal and X chromosome linked sequences and mouse genome-wide sequences were taken from Smit (1999). Separate values for mouse autosomes and X chromosome were not available. Because the content of interspersed repeats is related to the G+C content, the values are given for sequences that show G+C contents similar to the imprinted regions analyzed here.
