To commemorate the Wellcome Trust Sanger Institute turning 25 in 2018, the Institute and its collaborators are sequencing 25 new genomes of species in the UK representing its biodiversity. The final five species were chosen by thousands of school children and members of the public around the globe, who participated in the 25 Genomes Project online vote. This infographic shows where the species are in the UK and the size of their genomes.
