We have developed a general approach to the assessment of short autosomal DNA segments. Each such segment includes at least one single nucleotide polymorphism (SNP) and exactly one short tandem repeat (STR) locus. These two types of genetic markers have dramatically different mutation rates, and therefore provide complementary evolutionary information. We call the combination of a SNP and an STR a "SNPSTR", and have developed a simple, rapid method for empirically determining gametic phase for double (or triple) heterozygotes.
