Genetic variation at five trimeric and tetrameric tandem repeat loci in four human population groups.

Genomics - 1 Feb 1992

Edwards A, Hammond H A, Jin L, Caskey C T, Chakraborty R

Abstract excerpt

Trimeric and tetrameric short tandem repeats (STRs) represent a rich source of highly polymorphic markers in the human genome that may be studied with the polymerase chain reaction (PCR). We report the analysis of a multilocus genotype survey of 97-380 chromosomes in U.S. Black, White, Mexican-American, and Asian populations at five STR loci located on chromosomes 1, 4, 11, and X. The heterozygote frequencies of...
