Abstract
Drosophila pseudoobscura females show a positive bias toward mating with males whose proportion in the population is low. They can perform this discrimination even when three strains of males are present. The olfactory recognition required for this discrimination entails a hierarchically ordered recognition system and a natural unit of olfactory strength.Keywords
