n, number of individuals. Genome size estimates are presented separately for nuclei stained with DAPI (relative genome size) and PI (absolute genome size). Note that not all samples were analyzed with PI and that DAPI estimates are affected by potential differences in AT/GC ratios between the sample and the size standard.
