Figure 4 in Peaceful revolution in genome size: polyploidy in the Nabidae (Heteroptera); autosomes and nuclear DNA content doubling

Figure 4. Comparison of three alternative hypotheses on the ancestral 2n number of chromosomes of Nabidae: fusions, proposed by Nokkala et al. (2007); autosomal polyploidy, suggested by Kuznetsova & Maryańska-Nadachowska (2000) and supported by nuclear DNA content data from the present study; and the hypothetical fission theory. Abbreviations: 2C, nuclear DNA content; F, autosomal fusions; Fis, fissions; P, polyploidy.
