Comparison of zebrafish core MHC haplotypes. Genes highly conserved with the reference haplotype B are shown in blue, and these highly conserved relationships are illustrated with blue shading. Genes divergent from the reference haplotype B are shown in red, and divergent gene relationships with haplotype B are illustrated with red shading. Haplotype A is part of an alternative haplotypic assembly of sequences derived from AB zebrafish (VEGA59 chromosome AB: 9329627–9629628), haplotype B is from the reference genome derived primarily from Tuebingen zebrafish (Zv9 chromosome 19: 7623109–78026601), and haplotype D was obtained by de novo assembly of genomic sequences from CG2 clonal golden zebrafish (this study).
