Phylogenetics of Hiv
A phylogeny is a set of relationships among groups of genes or organisms that reflects their evolutionary history. Inferring a phylogeny is an estimation procedure, a statistical inference of a true phylogenetic tree that is unknown. However, the aim of the phylogenetic analysis is not merely the reconstruction of a tree topology; the phylogeny provides a powerful framework in which several hyp...
متن کاملThe power and pitfalls of HIV phylogenetics in public health.
Phylogenetics is the application of comparative studies of genetic sequences in order to infer evolutionary relationships among organisms. This tool can be used as a form of molecular epidemiology to enhance traditional population-level communicable disease surveillance. Phylogenetic study has resulted in new paradigms being created in the field of communicable diseases and this commentary aims...
متن کاملRational disagreements in phylogenetics.
This paper addresses the general problem of how to rationally choose an algorithm for phylogenetic inference. Specifically, the controversy between maximum likelihood (ML) and maximum parsimony (MP) perspectives is reframed within the philosophical issue of theory choice. A Kuhnian approach in which rationality is bounded and value-laden is offered and construed through the notion of a Style of...
متن کاملWeighted quartets phylogenetics.
Despite impressive technical and theoretical developments, reconstruction of phylogenetic trees for enormous quantities of molecular data is still a challenging task. A key tool in analyses of large data sets has been the construction of separate trees for subsets (e.g., quartets) of sequences, and subsequent combination of these subtrees into a single tree for the full set (i.e., supertree ana...
متن کاملEntanglement, Invariants, and Phylogenetics
This thesis develops and expands upon known techniques of mathematical physics relevant to the analysis of the popular Markov model of phylogenetic trees required in biology to reconstruct the evolutionary relationships of taxonomic units from biomolecular sequence data. The techniques of mathematical physics are plethora and have been developed for some time. The Markov model of phylogenetics ...
