Frequencies of microsatellite births (A), deaths (B), and stationary loci (C) in different Alu subfamilies along the Alu consensus sequence divided into 20-bp bins, and “frequency per alignment count” (see Methods) of microsatellite births (D), deaths (E), and stationary loci (F) in L1PA subfamilies along the L1PA consensus sequence divided into 60-bp bins (and corrected for L1PA sequence representation in alignments). In each plot, bars are decomposed and color-coded by different Alu/L1 subfamilies and by GC richness of the corresponding microsatellites (above and below horizontal midline, respectively).
