Histogram for the number of blocks according to the number of distinct haplotypes in a block. The blocks are obtained on the basis of a data set of human chromosome 21 from Patil et al. 2001, using the dynamic programming algorithm (Zhang et al. 2002b). The number of tag SNPs in each block, measured by f(·), is defined as the minimum number of SNPs that can distinguish at least 80% of unambiguous haplotypes.
