图3 COI基因中介网络图。连接点数字表示核苷酸转换的位置; 圆的大小对应单倍型频率, 不同鸡品种用不同颜色标注, 品种代号同表1。(a)中国12种255只乌骨鸡个体的24个COI单倍型。(b) 384只鸡个体的41个COI单倍型中介网络图。

Fig. 3 Median-joining network based on COI gene. The links are labeled by the nucleotide positions to designate transitions. Cycle size is roughly proportional to the haplotype frequency, the breeds are indicated by different colors, breed codes are the same as in Table 1. (a) Median-joining network of 24 COI haplotypes deteced in the samples of 255 individuals of 12 Chinese black-bone breeds. (b) Median-joining network of 41 COI haplotypes deteced in the samples of 384 individuals.
