On the use of star-shaped genealogies in inference of coalescence times.

Genetics - 1 Aug 2003

Rosenberg Noah A, Hirsh Aaron E

Abstract excerpt

Genealogies from rapidly growing populations have approximate "star" shapes. We study the degree to which this approximation holds in the context of estimating the time to the most recent common ancestor (T(MRCA)) of a set of lineages. In an exponential growth scenario, we find that unless the product of population size (N) and growth rate (r) is at least approximately 10(5), the "pairwise comparison estimator"...
