I. Liste et B. Caeiro, DISTRIBUTION OF ITI PHENOTYPES IN THE IBERIAN PENINSULA - NEGATIVE CORRELATION BETWEEN ITI-ASTERISK-3 FREQUENCIES AND LATITUDE IN HUMAN-POPULATIONS, American journal of human biology, 6(5), 1994, pp. 593-597
The molecular phenotypes of ITI were analysed in samples from seven po
pulations of the Iberian Peninsula (Galicia, Central Portugal, Castill
a-Leon, Castilla-La Mancha, Extremadura, Western Andalusia, and Easter
n Andalusia) by means of IEF in ultrathin layer polyacrylamide gels fo
llowed by immunofixation-silver staining. The observed ITI3 frequenci
es exhibit the highest values thus far reported in European population
s. Regression analysis between ITI3 frequencies and latitude reveals
a negative correlation (r = -0.8798, P < 0.001). (C) 1994 Wiley-Liss,
