Chromosome locations of the CAM loci in the chicken and zebra finch genomes. Gga, chicken (Gallus gallus) chromosome. Tgu, zebra finch (Taeniopygia guttata) chromosome. The exact chromosomal locations of the loci (in base pairs) are provided in Table 2. Those loci underlined are less than 5Mb apart and may display linkage disequilibrium.
