There are three types of inherited CVD: monochromacy, dichromacy and anomalous trichromacy.
Besides the relatively rare monochromacy (light/dark contrasts only), two main types of dichromacy or constrained trichomacy are observed among the male population: Either one of the cone cell subclasses is lacking entirely (about 2%) or it is anomalous (about 6%).
While cone monochromacy on land is rare, it may be a common strategy in the marine environment.
