Stereospecific analysis reveals that the distribution of fatty acids is nonrandom among the three positions of triglyceridcs from the maize ( Zea mays L.) strains, Illinois High Oil (IHO), R84, and C103. Positional specificity and fatty acid concentration effects are the major factors contributing to differences in fatty acid distribution in triglycerides. Both are under genetic control. The loci affecting levels of linoleate in IHO, R84, and C103 do not operate at the level of positional specificity; rather, the control is exerted in the concentration effect. Maternal effects detected in the reciprocal F 1 's are a function of concentration, and not positional specificity.
