IGF1 sites potentially associated with body size. a) Dog site rs22397284 in the context of a multiple alignment with cetaceans and the human genome. The sequences here are reverse complements of those shown in (Plassais et al. 2022), Fig. 3. rs22397284 is marked by an arrow. b) Phylogenetic tree of 11 cetaceans considered in this analysis, generated by Timetree. The 3 clades discussed in the text and the Orca are shown in different colors. c) An example type 1 site, blue whale chromosome 10 position 85,169,891. d) An example type 2 site, blue whale chromosome 10 position 85,160,822. See Table 3 for site types.
