An X-chromosome pentaplex in two linkage groups: haplotype data in Alagoas and Rio de Janeiro populations from Brazil.

Genotype data were obtained for five X-Chr STRs (DXS10079, DXS10074, DXS10075, DXS7424 and DXS101) in two different populations from Brazil, namely Alagoas and Rio de Janeiro. Observed genotype distributions in female samples for each locus do not show deviations from Hardy-Weinberg equilibrium expectations. Gametic association was tested for all pairs of loci in male samples.
