From: Control of chicken CR1 retrotransposons is independent of Dicer-mediated RNA interference pathway
Phylogenetic analysis of the 5'UTR promoters of all chicken CR1 subfamilies. The tree is constructed based on sequence diversity of all 5'UTRs, including functional and non-functional CR1 elements, using the neighbour-joining method. Each CR1 subfamily is shown in different colours, and CR1-F subfamily with more than one branch is shown in the same (red) colour.
