The concept of kinship permeates many domains of fundamental and applied
biology ranging from social evolution to conservation science to
quantitative and human genetics. Until recently, pedigrees were the gold
standard to infer kinship, but the advent of next generation sequencing
and the availability of dense genetic markers in many species make it a
good time to (re) evaluate the usefulness of genetic markers in this
context. Using three published data sets where both pedigrees and markers
are available, we evaluate two common and a new genetic estimator of
kinship. We show discrepancies between pedigree values and marker
estimates of kinship, and explore via simulations the possible reasons for
these. We find these discrepancies are attributable to two main sources:
pedigree errors and heterogeneity in the origin of founders. We also show
that our new marker-based kinship estimator has very good statistical
properties and behavior, and is particularly well suited for situations
where the source population is of small size, as will often be the case in
conservation biology, and where high levels of kinship are expected, as is
typical in social evolution studies.
