Distribution of ITI phenotypes in the Iberian Peninsula: Negative correlation between ITI*3 frequencies and latitude
1Departamento de Antropoloxía, Facultade de Bioloxía, Universidade de Santiago, 15706 Santiago de Compostela, Galicia, Spain.
Abstract:
The molecular phenotypes of ITI were analysed in samples from seven populations of the Iberian Peninsula (Galicia, Central Portugal, Castilla-Leon, Castilla-La Mancha, Extremadura, Western Andalusia, and Eastern Andalusia) by means of IEF in ultrathin layer polyacrylamide gels followed by immunofixation-silver staining. The observed ITI*3 frequencies exhibit the highest values thus far reported in European populations. Regression analysis between ITI*3 frequencies and latitude reveals a negative correlation (r = -0.8798, P < 0.001). © 1994 Wiley-Liss, Inc.

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
