This option is very important: in the first case, it implies that all individuals are somewhat all-knowing,​ or that their ability to distinguish between mates is not influenced by social environment (local availability of phenotypes). The second case on the opposite implies that the locally available phenotypes define the whole span of preference expression, whatever the actual range of variation in phenotype. It also means that individuals can actually clearly distinguish between two very similar phenotypes.
