Physical clustering of oyster ANTP class genes, excluding Hox genes. Most ANTP class genes show no clustering in the oyster genome. Linkages found between ANTP genes (in red) are shown for five scaffolds of Pacific oyster genome assembly version 9.1. Scaffolds are not represented to scale, numbers indicate the nucleotide positions defining each genomic region within a scaffold. When the genes shown are not located at the end of a scaffold, no other homeobox genes were found for the next five gene models. Dashed lines indicate the presence of additional genes in the scaffold; black circles denote the end of scaffolds.
