The accompanying pedigree and gel diagram show the molecular phenotypes obtained from genomic DNA samples. The bands are characteristic DNA fragments that distinguish two alleles of a single gene. What mode of inheritance does the pedigree suggest? On the basis of this hypothesis, and using A1 to represent the allele associated with the 4-kb band and A2 to represent the allele associated with the 9-kb band, deduce the genotype of each individual in the pedigree.
