There are four major alleles at this locus known as 1, 2, 3, and 4. How many different genotypes are possible for these four alleles? A. 8 B. 10 C. 12 D. 16 E. 24 Thank you BrainMass!

Forensic DNA Fingerprinting and the Variations of VNTR

2. The VNTR alleles analyzed in forensic DNA fingerprinting experiments are highly variable from individual to individual. How do the many VNTR alleles at a single locus differ from each other?
