Abstract
We propose a probability model to impute missing identicalβbyβdescent (IBD) vectors for linkage analysis, when adjacent marker loci are typed and interference is estimable. A chromosomeβbased IBD distribution, conditioned on available marker data, is computed using a fast algorithm to estimate the joint probability of genes IBD at several equally spaced linked loci. Weighted IBD vectors are then used in various test statistics for linkage analysis. As an example, we analyzed the 18 affected sib pairs in the GAW9 Problem 1 data set using Risch's lodβscore test.

Genes which confer a disease when mutated, or for which population variability contributes to a quantitative trait such as longevity or disease susceptibility, can be localized in the genetic map by use of an appropriately dense set of polymorphic DNA markers. Here we describe an anchor PCR method f
