    Sammanfattning : Abstract The existence of conflicting genealogies of different genes through the evolution of species complicates the inference of phylogenetic relationships. The Multispecies Coalescent (MSC) model provides a theoretical background that account for the stochasticity in the genealogical process, thus providing systematists with a potentially objective way of testing alternative hypotheses of putative species.

  2. 2. Phylogenetic Support and Chloroplast Genome Evolution in Sileneae (Caryophyllaceae)

    Författare :Per Erixon; Bengt Oxelman; Sean Graham; Uppsala universitet; []
    Nyckelord :Biology; Phylogenetics; Bayesian inference; Bootstrapping; cpDNA; Sileneae; Interspecific chloroplast recombination; Hybridization; clpP; Positive selection; Extreme substitution rates; Biologi;

    Sammanfattning : Evolutionary biology is dependent on accurate phylogenies. In this thesis two branch support methods, Bayesian posterior probablities and bootstrap frequencies, were evaluated with simulated data and empirical data from the chloroplast genome. LÄS MER
