A 900 bp regiоn оf а gene is аmplified with а single primer pair; the primers bind at the twо ends of the region, so the undigested product is 900 bp long. Two alleles occur in the population and differ by a single nucleotide: Allele M1 contains an EcoRI site 300 bp from the 5′ end of the amplified product. Allele M2 — the single nucleotide difference destroys that site, so the product contains no EcoRI site. The PCR product from each individual is digested to completion with EcoRI and separated on a gel.
