From: Impact of ploidy level on the distribution of Pokey element insertions in the Daphnia pulex complex
Relationship between the total number of Pokey insertions outside rDNA estimated using qPCR and TE display. Empty symbols are diploids and solid symbols are polyploids. Empty orange circles: diploid hybrids with D. pulex mitochondrial haplotypes; solid orange circles: triploid hybrids with D. pulex mitochondrial haplotypes; solid square: D. middendorffiana; empty black triangles: diploid D. tenebrosa; solid black triangles: triploid D. tenebrosa; solid red triangle: introgressed D. tenebrosa with a D. pulex nuclear genome; solid green diamond filled with orange: triploid hybrids with D. pulicaria mitochondrial haplotypes. Thin lines represent lower (slope = 1 and y-intercept = 0) and upper limits for diploids (slope = 2 and y-intercept = 0) and triploids (slope = 3 and y-intercept = 0) of Pokey insertion number (see Methods). Thick lines are linear regressions estimated from the data.
