Figure 4From: Simple sequence repeat variation in the Daphnia pulex genomeRepeat heterozygosity, point mutation heterozygosity and raw counts for homopolymers (A, C, E) and dimers (B, D, F). Black lines and squares correspond to A/T homopolymers, red lines and squares correspond to C/G homopolymers. Colors corresponding to the dimers are green:AC/CA/GT/TG, blue:AG/GA/CT/TC, grey:AT/TA, magenta:CG/GC. (A) Percent repeat heterozygosity for homopolymers A/T (r2= 0.925, p < 1e-11) and C/G (r2= 0.899, p < 1e-10) with increases in heterozygosity highest between 7-11 repeats. C/G heterozygosity is approximately 3-fold higher than A/T heterozygosity. (B) Percent repeat heterozygosity for dimers with AC> AG> AT > CG (r2 = 0.862, p < 1e-5; r2 = 0.891, p < 1e-5; r2 = 0.736, p < .01; r2 = 0.539, p < .2). (C) Point mutation per nucleotide for homopolymers C/G (r2 = 0.905, p < 1e-12) and A/T (r2 = 0.446, p < .01), highest increase in polymorphism occurring at 7-11 repeats. (D) Percent point mutation/per base heterozygosity of microsatellites, AT/CG loci with higher proportions of point mutations than AC/AG types. (E) Raw genome counts of A/T and C/G homopolymers with frequency changes between 7-11 repeats. (F) Raw counts of dimers AC/AG/AT/CG.Back to article page
