Annual percentage yield (APY) represents the rate of interest on a certificate of deposit, savings account or other investment. Typically annual percentage yield is calculated for accounts receiving compounded interest rather than a simple interest reflecting the nominal (official) interest.rate.
Molecular phylogeny is the use of the structure of molecule s to gain information on an organ ism's evolution ary relationships.The result of a molecular phylogenetic ana lysis is express ed in a so-called phylogenetic tree.Molecular phylogeny is the use of a gene 's molecular character istics to class ify an organ ism and to place it on a map of evolution ary relationships known as the phylogenetic tree.olecular phylogeny indicates that human pubic lice diverged from gorilla lice as recently as 3.3 MYA [3], whereas the chimp and human host lineage split from the gorilla lineage at least 7 MYA (Figure 3).
Phylogenetic systematics, a.k.a. evolutionary trees : Reading trees: A quick review. A phylogeny, or evolutionary tree, represents the evolutionary relationships among a set of organisms or groups of organisms, called taxa (singular: taxon).he tips of the tree represent groups of descendent taxa (often species) and the nodes on the tree represent the common ancestors of those descendants. Two descendents that split from the same node are called sister groups. In the tree below, species A & B are sister groups  they are each other's closest relatives.
