Question - Explain briefly what are Alu insertions and VNTRs. Why these polymorphisms can be used for DNA fingerprinting? What is the genotype distribution for the PV92 Alu insertion? (i.e. percentage of homozygous and heterozygous individuals on the gel for your section)? What is the genotype distribution for VNTRs? How many alleles do you think are present in the students' population?
