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?
A.Allele-specific oligonucleotide probes
B.DNA hybridization chips
C.Small interfering RNA
D.Restriction fragment length polymorphisms
E.Variable number tandem repeats

The correct answer is D.
Restriction fragment length polymorphisms.RFLP's are useful when a researcher is looking for genetic variabilty
Allele-specific oligonucleotide probes (A) is used to identify a particular mutation,, or to count chromosomes.
B is used to identify a set of single nucleotide polymorphisms.it’s most commonly used to measure gene expression in certain cells or tissues.
siRNAs © would be used to modulate gene expression at the transcriptional/post-transcriptional level.
VNTRs (E) are used for DNA fingerprinting
