The problem of resolving genotypes into haplotypes, under the perfect phylogeny model, has been under intensive study recently. All studies so far handled missing data entries in a heuristic manner. We prove that the perfect phylogeny haplotype problem is NP-complete when some of the data entries are missing, even when the phylogeny is rooted. We define a biologically motivated probabilistic mo...

The hagfish, an Agnathan cyclostomes is the most primitive of true vertebrates as evidenced by its formed, circulating RBC and haemaocytopoietic tissue in the submucosa of the gut tract.(1) Interested in the phylogeny of the IR the authors were prompted to ship from the Scripps Institute of Oceanography and the kindness of Dr. David Jensen, about 120 California hagfish to explore this question....

The sand termite Psammotermes allocerus is widely distributed in southern Africa. To investigate the genetic diversity of this species 113 samples were collected arid regions South Africa, Namibia and Angola fairy circles also landscapes without circles. mitochondrial markers COI COII selected to perform Bayesian Inference analysis. phylogenetic tree composed eight well-supported groups within ...

An acyclic digraph in which every vertex has indegree at most i and outdegree j is called an (i,j) for some positive integers j. Lee et al. (2017) studied the phylogeny graphs of (2,2) digraphs gave sufficient conditions necessary a to have chordal graph. Their work was motivated by problems related evidence propagation Bayesian network it useful know moral (phylogeny are theory). In this paper...
