Trees and/or networks to display intraspecific DNA sequence variation?

摘要: Phylogenetic trees and networks are both used in the scientific literature to display DNA sequence variation at intraspecific level. Should we rather use or networks? I argue that process of inferring most parsimonious genealogical relationships among a set sequences should be dissociated from problem displaying this information graph. A network graph is probably more appropriate than strict consensus tree if many alternative, equally parsimonious, genealogies included. Within maximum parsimony framework, current phylogenetic inference network-building algorithms unable guarantee finding all (MP) connections. In fact, each approach can find MP connections other does not. Although it possible improve least approach, implementations these such advisable approaches increase probability sequences.
