Table 4 Comparison of discrepancies between beluga (Delphinapterus leucas) and narwhal (Monodon monoceros) reference genomes. For beluga, assemblies were compared to Dl₅, as this was the most contiguous; for narwhal, the assembly of Damas et al. [1] was compared to Mm₃. Discrepancies as a percentage of the total evaluated reference genome are presented in parentheses
