Abstract

The analysis of STR HUMTH01 in four populations (Galicia, SE Spain, Morocco, Cape Verde) was carried out, with up to 8 alleles being found. The frequencies of these alleles determine values of heterozigosity ranging from 0,826 detected in Cape Verde to 0,778 in Morocco.A global comparison of world populations shows clear patterns of differentiation among the main human groups, both by way of the analysis of allele distribution profiles and by the application of a Correspondence Analysis. Caucasian populations are mainly characterised by the highest frequencies in allele 9.3, Mongoloids by a very high frequency of allele 9 and Negroids show the highest frequencies for allele 7 and mainly 8. A significant negative correlation (r=−0,916, p<0,001) found in the relationships between alleles 9 and 9.3 seems to suggest the participation of non-random evolutionary forces in the population dynamics of this marker.
