star-like tree

The resolution of time intervals for possible population expansions requires the demonstration of star genealogies rather than their prior assumption.

methods matter

What remains from one branch is independent from the others, and the compound distribution is the product of individual branches. Star-like genealogies are by far the easiest to analyze, as this model bypasses all the difficulties of translating a set of mosaic haplotypes into a specific genealogy.

star-like tree

In star genealogies, the distribution of chromosomal regions inherited from a single common ancestor is unambiguously defined by a single parameter, branch length.
