Sequencing 101: Looking Beyond the Single Reference Genome to a Pangenome for Every Species

What is a Pangenome? A pangenome identifies which portions of the genome are unique and which overlap and are therefore core to the species. Unless you have an identical twin, no other person has a genome that is identical to yours. The same is true for other animal, plant, and microbial species that reproduce sexually: the genomes of individuals are unique. Less well known, but equally true, is that individual members of a species do not always share even the exact same genes. Nevertheless, scientists mostly use a single reference genome to represent an entire species: one human genome, one…
