The OlfC gene cluster of the Lake Victoria cichlid Haplochromis chilotes. The cluster region spans more than 1 Mb covered by eight BAC clones, in which 61 intact OlfC genes are arranged. OlfC genes were categorized into 16 subfamilies according to Hashiguchi and Nishida (2006). Gray bars indicate the BACs that cover the region. The ID and the length of each BAC clone are indicated above each gray bar. The genes neprilysin and phospholipase C-η1 were used as landmarks at the 5′- and 3′-ends, respectively, of the cluster region. Genes in the sense orientation are shown above the black line, and genes in the antisense orientation are shown below the black line.
