Figure 3From: Duplication, concerted evolution and purifying selection drive the evolution of mosquito vitellogenin genesOrthologous/paralogous relationship of Vtg genes in Cx. tarsalis and Cx pipiens. Orthologous and paralogous gene relationships were determined by nucleotide identity of their 5'promoter regions. The thin solid lines represent 5'promoter and 3'end regions, open boxes represent coding sequences, and the filled box represents intron sequence. Sequence direction (5' and 3') and the number of nucleotides with high identity between orthologs in their 5' promoter region are indicated above the sequences; the percentage of nucleotide identity is listed below the sequence.Back to article page
