Fig. 3From: Diversity of P-element piRNA production among M' and Q strains and its association with P-M hybrid dysgenesis in Drosophila melanogaster Characterization of the natural strains based on piRNA levels in F1 progenies. Relationship between the expression levels (RPM) of P-element ping-pong-paired piRNAs in F1 ovaries and total P-element piRNAs in embryos.
