Restriction fragment length polymorphisms are good anthropological markers for discriminating geographically distinct populations at both the allele and the haplotype level. Two communities of African ancestry and ladinos, mestizos, and mulattoes living in the Esmeraldas province in northwestern Ecuador were analyzed for three RFLPs (EcoRI, RsaI, and MspI) of the COL1A2 gene. Also, the same markers were studied in a population sample from Spain to compare the allele and haplotype frequencies of the Esmeraldas populations with those of their representative European parental population.
