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?
- Allele-specific oligonucleotide probes
- DNA hybridization chips
- Small interfering RNA
- Restriction fragment length polymorphisms
- Variable number tandem repeats
