Unformatted text preview: - make a crossbar for every base-change event that occurs - label the cross bar with the locus # and the base change (1C =change to C at 1 st locus) - at each node write out the nucleotide sequence (AGGTGA =node for base ancestor) - if there is a change from the nodes sequence, there should be a crossbar...
