Diego blood factor is characteristic of Mongoloid populations. A study of 152 samples from Mexican Indians (Tlaxcaltecans) revealed this factor in 20.39 percent of the cases. Analysis of 30 Indian matings with 62 children support the hypothesis that the Diego antigen is transmitted through a gene capable of expressing itself in a single or double dose.
