title: Deletion mapping of polymorphic loci by apparent parental exclusion.
abstract: Deletion of a chromosome region containing a polymorphic marker may result in apparent parental exclusion at that locus. We present a general method for calculating the probability that deletion at a specific locus would have such an effect. For many autosomal loci this probability is substantial, justifying attempts at deletion mapping in most cases. This method may be especially valuable in assigning DNA restriction fragment polymorphisms to chromosome regions.
