Abstract

Two male sibs believed to be examples of meiotic recombinants between the closely linked loci for G6PD deficiency of Mediterranean type and severe deutan color blindness proved to be simple segregants of a triplo-X mother of genotype d--GdMediterranean/d+GdMediterranean/d+GdB. This finding suggests that in Sardinia the linkage between the two loci under consideration may be tighter than previously assumed.
