Figure 2From: Origins of amyloid-βPhylogenetic Relationships of 103 members of the Amyloid-β Precursor Protein Gene Family. Shown are: (a) Phylogram showing the evolutionary relationships among the nucleotide sequences of the AβPP gene family; (b) Phylogram for the corresponding protein sequences. Trees were generated by maximum parsimony methods. Scale bars indicate character changes contributing to branch lengths.Back to article page
