图3 基于mtDNA COX1单倍型构建的邻接系统进化树。字体加粗的Hap-1-Hap-4为本研究报道的纽芬兰大浅滩的单倍型。进化树上括号内的字符为相应序列的GenBank注册号, 斜线两侧的数字为邻接和最大似然算法自展值(1,000次重复)。箭头所示为Coyer等(2011)报道的COX1单倍型。每个COX1单倍型在不同位置(即比对碱基上方的数字)的碱基变异用红色凸显。

Fig. 3 Neighbour joining phylogenetic tree constructed using mtDNA COX1 haplotypes. Hap-1-Hap-4 in bold font are haplotypes identified from the Grand Banks of Newfoundland in this study. The characters in parentheses are GenBank accession numbers for each sequence, and the numbers on both sides of the slash are bootstrap values of neighbour joining and maximum likelihood algorithm (1,000 replicates). The arrow indicates the COX1 haplotypes reported by Coyer et al (2011). The nucleotide variations of each COX1 haplotype at different numbering sites (i.e. the numbers above the aligned nucleotides) are highlighted in red color.
