Fig. 5From: A study of the composition of the Obsoletus complex and genetic diversity of Culicoides obsoletus populations in SpainMedian-joining network showing the relationship of the 23 haplotypes of 457-bp in length. Node size represents the number of sequences that comprise each haplotype. Each geographical location is color coded to show its haplotype frequencies. Perpendicular lines indicate nucleotide changes. For abbreviations, see Fig. 1Back to article page
