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).
Molecular approaches to systematics for us to think about the rates of molecular evolution. If DNA or proteins evolved at a constant rate in all species, then one could use estimates of sequence divergence to build very reliable phylogenies.If there was a molecular clock we could determine the true phylogeny.legant molecular methods available, a lot of work but provides lots of data. Each nucleotide position is a character and the actual nucleotide that is present at that site is the character state. A character can be phylogenetically informative when nucleotide changes are shared by two or more taxa.
