siRNAs and piRNAs abundance during conversion. Size distribution of ovarian small RNAs isolated from the P(lArB)-PI, subline D (A), or the P(lArB)-MI subline H (B) matching to T3 and P(lArB) in G1, G2, G3, and G4. When paternally inherited, P(lArB) is converted for piRNA synthesis progressively across generations, while T3 is converted from the first generation (G1). C Size distribution of small RNAs isolated in the G1 and G4 progenies of females containing P(lArB) crossed with males containing P(lacW) mapped on the white sequence. In this context, white gene is progressively converted (Fig. 4F). The ratio number of normalized 23–29-nt over 21 nt is indicated for the P(lArB) panel
