Note

These online heredity calculators use simplified models to calculate traits and their certainty is far from 100% due to the fact that human genetics is far more complex than a simple mendelian dominant/recessive model. Personal Report and Heredity Report give better results, providing that you had your genome sequenced by a commercial personal genomics companies like 23andMe, deCODEMe, Ancestry.com or Family Tree DNA.

In any case, these reports do not substitute for clinical tests, genetic counseling or paternity/maternity tests. If you have questions about your genetic heritage, its relation to diseases or any other health-related issues you should consult your doctor.

The pigmentation of the iris in humans varies from light brown to black, depending on the concentration of melanin in the iris pigment epithelium (located on the back of the iris), the iris stroma and the cellular density of the stroma. Eye color is an inherited trait influenced by more than one gene.

This calculation uses a two-genes(brown vs non-brown and blue vs green) co-dominance model.

Hair Color

Hair color is determined by the amount of two pigments - brown-black eumelanin predominates in black and brown hair and red-yellow pheomelanin in red hair. Blond hair contains low levels of both pigments. The genetics of human hair color are not firmly established, but there are indications that multiple genes determine whether a person will have brown, blond or red hair.

This calculation uses a two-genes(brown vs non-brown and red vs non-red) co-dominance model.
