Fig. 2: Phylogeny relating the DNA sequences that cover the core Neanderthal haplotype in individuals from the 1000 Genomes Project and Neanderthals.
From: The major genetic risk factor for severe COVID-19 is inherited from Neanderthals

The coloured area highlights the haplotypes that carry the risk allele at rs35044562—that is, the risk haplotypes for severe COVID-19. Arabic numbers indicate bootstrap support (100 replicates). The phylogeny is rooted with the inferred ancestral sequence of present-day humans. The three Neanderthal genomes carry no heterozygous positions in this region. Scale bar, number of substitutions per nucleotide position.
