A physical dichotomy between males and females of a particular species

sex·u·al di·morph·ism

(sek'shū-ăl dī-mōr'fizm)

sexual dimorphism

the presence in a population of two sexes each with a different PHENOTYPE, a classic example of a GENETIC POLYMORPHISM. The underlying mechanism varies in different organisms, but is often controlled by genes on special SEX CHROMOSOMES (see SEX DETERMINATION).
