Question

An autosomal recessive disorder with alleles A and a has been linked to a VNTR. The recombination frequency of the disease gene and the VNTR is 10.7%. The accompanying pedigree shows a two-generation family in which the disease is present. The VNTR has two alleles V1 and V2 and the gel electrophoresis pattern of each family member has been shown below.

Based on this information, what is the genotype of II-5 for VNTR.
