Fig. 6From: Association of zygotic piRNAs derived from paternal P elements with hybrid dysgenesis in Drosophila melanogasterThe KP-element mRNA and P-element piRNA in F1 ovaries are correlated to the GD scores in F1 and F2 hybrids (a) The relationship between the expression levels of piRNAs (y-axis) and mRNA (x-axis) of P elements in F1 ovaries. The Pearson’s R and p values are shown on the top. b A dendrogram of the five natural strains constructed by hierarchical clustering based on the data shown in panel A. c The results of the multiple regression analysis for GD scores in F1 (as the objective variable) with the levels of KP-element mRNA and P-element piRNAs in F1 ovaries (as explanatory objectives). d The relationship between the expression levels of piRNAs in F1 hybrids (y-axis) and GD scores of F2 hybrids (x-axis). Pearson’s R and p values are shown on the top. e A dendrogram constructed of the five natural strains by hierarchical clustering based on the data shown in panel D. f The results of the multiple regression analysis for GD scores in F2 (as the objective variable) with the levels of KP-element mRNA and P-element piRNAs in F1 ovaries (as explanatory objectives)Back to article page
