The difference between a pangenome and a supergenome.
Pan genome is homologous to each other. I.e., it is derived from the recent common ancestor(s).
Supergenome can be heterogeneous. I.e., it is derived from not so recent common ancestors where we can not easily establish genomic homology. The genomes are from different species. An example of a supergenome is a human body's genomes that include a human genome, gut microgenomes, fugal genomes on skins, and pathogenomes in the body.
