Impact of ploidy level on the distribution of Pokey element insertions in the Daphnia pulex complex

Abstract

These results suggest a lack of increase in the number of Pokey insertions following polyploidization but higher availability of Pokey insertion sites in polyploids than in diploids. Compared to previous TE display and qPCR results, the load of Pokey insertions in hybrid diploids was higher than in non-hybrid sexual and asexual diploids, which suggests an increase in the density of Pokey insertions following hybridization.
