From: A comprehensive analysis of the germline and expressed TCR repertoire in White Peking duck

Phylogenetic analyses of the TCR V gene segments from representative mammalian, avian and amphibian species, Vα and Vδ (a), Vβ (b) and Vγ (c). The unrooted trees were constructed using the neighbour-joining method with nucleotide sequences corresponding to FR1 through FR3. Duck V gene segments are indicated in bold. Numbers next to the branches show the percentages of the nodes in 1,000 bootstrap replicates.
