Figure 4From: Copy number variation of ribosomal DNA and Pokey transposons in natural populations of DaphniaHaploid Pokey number inside and outside of rDNA in D. pulex and D. pulicaria. L isolates are from lakes (D. pulicaria) and P isolates are from ponds (D. pulex). (a) gPokey and rPokey number in each isolate. rPokey is inserted in 28S genes. gPokey was calculated as (total Pokey- rPokey). (b) Correlation between gPokey and rPokey. D. pulicaria (-3) refers to the analysis done after excluding the three isolates with high Pokey load (see text).Back to article page
