The following is a list of genetic traits which are heritable in humans. Remember that a person displaying the recessive trait is homozygous, and cannot transmit the dominant form of the trait to his or her progeny. Alternatively, a person displaying the dominant trait (phenotype) may be either homozygous, in which case all of the progeny will display the trait, or heterozygous, in which there is a 50% chance that any given offspring will display the trait if the other mate displays the recessive trait.
Non-pathological:
| DOMINANT TRAIT | RECESSIVE TRAIT (Allelic to left column) |
| Brown eyes
PTC taster Widow's Peak Middigital hair Tongue roller Detached earlobe A and B blood type (codominant) Rh positive blood type Pattern baldness (dominant in males) |
Blue eyes (more complex, simplified here)
PTC non taster Lack Widow’s peak Hairless mid digits Cannot roll tongue Attached earlobe Type O blood type Rh negative blood type Pattern baldness (recessive in females) |
Pathological:
| DOMINANT TRAITS | RECESSIVE TRAITS (Not alleles of left column) |
| Achondroplasia
Brachydactyly Congenital stationary night blindness Ehler-Danlos syndrome Fascio-scapulo-humeral muscular dystrophy Huntington disease Hypercholesterolemia Marfan Syndrome Nail-patella syndrome Neurofibromatosis Polydactyly |
Albinism
Alkaptonuria Atasia telangiectasia Color blindness Cystic fibrosis Duchenne muscular dystrophy Galactosemia Hemophilia Lesch-Nyhan syndrome Phenylketonuria Sickle-cell anemia Tay-Sachs disease |
