Multiple alleles interact to produce a trait in which neither dominant gene can produce its effect in the presence of the other. Traits have more than two alleles at a population level, although individuals still only get one from each parent. These alleles may exhibit classic dominance, they may mask each other, they may add to or subtract from each other, or some combination of these effects.
The best characterized example of multiple alleles in humans is the ABO blood groups, discussed in the Non-Mendelian Inheritance concept. Other human traits determined by multiple alleles would be hair color, hair texture, eye color, built, physical structures, etc.
