In humans, EcoRI site polymorphisms distinguish three wildtype alleles and one mutant allele (a through d, shown in red) for an autosomal recessive disease. In the figure shown here, each person's RFLP profile is shown directly below that person in the pedigree.
Provide RFLP patterns for each allele represented in this family, consistent with the gel profile, indicating the location of the probe and restriction sites that yield the bands seen on the gel.
