Figure 1:

(A) The heatmap shows the Hi-C contact map for the P. giblindavisi genome. The color code for each cell indicates the number of Hi-C read pairs identified for a specific pair of 250-kb windows. (B) The picture shows a sperm cell of P. giblindavisi whereby the chromosomes were stained by Hoechst 33342. The scale bar indicates 2 μm. The bar plots show the proportion of male meiotic cells and sperms with each chromosome number. (C) We defined 1-1 orthologs between P. giblindavisi and P. pacificus proteins using best reciprocal BLAST hits and assigned Nigon elements based on the location of the 1-1 ortholog in the P. pacificus genome. Each bar shows the number of orthologs from different Nigon elements across 500-kb windows of the P. giblindavisi chromosomes.
