Phylogenetic tree combined

By clicking submit bottun, after the AND combinations of several conditions, the content search area retrieve the selected GPCR genes that again appear on the chromosomal viewer, the phylogenetic tree viewer, and the lower scroll list page. 

Having estimated pairwise proximities, one needs to combine these into a phylogenetic tree. In general one can use a UPGMA-like algorithm and get the best-fit proximities to intermediate ancestors. However, if there are only two or three species the tree can be estimated more directly ... 

The explanations in this section and the details of Table 3.1 are summarized in Hg. 3.18 in which the provisional phylogenetic tree of Fig. 2.2 is combined with the occurrence of tropane alkaloids (two subclasses) and two other classes of metabolites by plotting four characters on this tree ...
