Abstract:Trees corresponding to Λ-and Ξ-n-coalescents can be both quite similar and fundamentally different compared to bifurcating tree models based on Kingman's n-coalescent. This has consequences for inference of a well-fitting gene genealogy as well as for assessing biological properties of species having such sample genealogies. Here, mathematical properties concerning clade sizes in the tree as well as changes of the tree when the samples are enlargened are highlighted. To be used as realistic genealogy models fo… Show more
