Figure 3

(a–d) The locations of presumptive lamprey-chicken orthologs (including duplicates) are plotted relative to their physical positions on chromosomes and scaffolds and are connected by colored lines. (a,b) Pairs of chicken chromosomes that correspond to a series of lamprey scaffolds. (a) Ten lamprey loci are present as duplicate copies in the chicken genome, and 59 are present as single copies. (b) Twelve lamprey loci are present as duplicate copies in the chicken genome, and 54 are present as single copies. (c,d) Pairs of lamprey scaffolds that correspond to individual chicken chromosomes. (c) Three chicken loci are present as duplicate copies on syntenic lamprey scaffolds. (d) Two chicken loci are present as duplicate copies on syntenic lamprey scaffolds. Asterisks indicate duplicates.
