Figure legends
Fig. 1 – Phylogeny of MCHR1 and MCHR1-like identified in
both tawny owl genomes in relation to other bird taxa. Bootstrap values
ML tree was condensed for bootstrap values >80%.
Alignments are shown partially to focus on colour-morph specific SNPs.
Fig. 2 – Percentage of individuals with genotype combinations of
candidate loci for each morph. “N” represent the number of individuals
carrying each respective genotype and/or genotype combination (Punnett
square-like diagram). The genomic landscape on which candidate loci was
found in the tawny owl genome (shown by a thin red bar) is depicted
parallel to the square diagram. Yellow polygons represent exons and blue
polygons introns, as predicted by the annotation tool. Below is the
orthology of the β-keratin (BISK1)-FTCD-CO6A2 region across bird
genomes, whose accession number can be consulted in the supplemental
information document.
Fig. 3 – Proposed research directions to investigate the relationship
between melanin pigmentation and melanin-phenotypes. Application to work
developed in tawny owls in this study; stars denote future research
avenues.
