Abstract
- A careful DNA analysis revealed a few differences in the DNA between the brothers. DerekAbbott University of Adelaide, Australia It is possible to determine the genetic difference between identical twins if you target single nucleotide polymorphisms (SNPs) in their DNA rather than the short tandem repeats (STRs) that are used for standard DNA tests. SNP analysis is much more finegrained, as each SNP represents a difference in a single nucleotide, the building block of DNA. [Extracted from the article]
