Clustermap evidencing presence/absence and abundance of the satDNAs across Alligatoridae species. Abundances were calculated as the log10 of the proportion of short reads masked as satDNAs with a maximum of 20% of divergence and normalized by single-copy genes. On the left, hierarchical calculated clusters; on the right, species name and the proposed phylogeny for the group with their respective divergence times, based on data generated by [65]
