The same haplotype block on six different homologous chromosomes from the population is shown below. The five SNPs in this block are genotyped on each chromosome; the rest of the DNA sequence (…..) is identical between the chromosomes.   1) How many different haplotypes can you see? [number] 2) Which combination of SNPs could be used as TAG-SNPs to identify the haplotype found in in this haplotype block? [TAGSNPS]
