We obtain exact expressions for the probability that no recombination has occurred in a sample or subsample. We obtain an approximation for the probability that no recombination that could give rise to a detectable recombination event (through the four-gamete test) has occurred. The probabilities can be used to obtain approximate distributions for the length of variously defined haplotypes around a polymorphic site. The implications of our results for data analysis, and in particular for detecting selection, are discussed.}, pages = {437--444}, title = {The Extent of Linkage Disequilibrium and Haplotype Sharing Around a Polymorphic Site}, volume = {165}, year = {2003} }
