A researcher has designed a study in which she will compare the variability of alleles for two hundred genes on four chromosomes between two populations: two thousand children with low-functioning autism and two thousand children with no developmental or other disorder. Which tool will be the most useful for identifying allele variability?

B.DNA hybridization chips
C.Small interfering RNA
D.Restriction fragment length polymorphisms
E.Variable number tandem repeats
