In classical genetics, codominance refers to the situation in which a heterozygous organism has a phenotype that demonstrates traits from both the dominant and the recessive genes. Unlike the similar situation of incomplete dominance, a codominant trait is not blended, but is independently and equally expressed. Wikipedia does not have an article with this exact name. ... In classical genetics, incomplete dominance refers to the situation where an organism demonstrates a blended or combined phenotype due to inheriting a heterozygous genotype (the situation when one of the alleles is dominant and the other recessive). ... Classical genetics consists of the techniques and methodologies of genetics that predate the advent of molecular biology. ... Heterozygote cells are diploid or polyploid and have different alleles at a locus (position) on homologous chromosomes. ... Jump to: navigation, search In biology and ecology, an organism (in Greek organon = instrument) is an assembly of organs that influence each other in such a way that they function as a more or less stable whole and have properties of life. ... The phenotype of an individual organism is either its total physical appearance and constitution, or a specific manifestation of a trait, such as size or eye color, that varies between individuals. ... In biology, a trait or character is a genetically inherited feature of an organism. ... In genetics, the term dominant gene refers to the an allele that causes a phenotype that is seen in a heterozygous genotype. ... In genetics, the term recessive gene refers to an allele that causes a phenotype (visible or detectable characteristic) that is only seen in a homozygous genotype (an organism that has two copies of the same allele). ... In classical genetics, incomplete dominance refers to the situation where an organism demonstrates a blended or combined phenotype due to inheriting a heterozygous genotype (the situation when one of the alleles is dominant and the other recessive). ...

The classic example of codominance is cattle. If a homozygous bull and homozygous cow mate (one being red and the other white), then the calves produced will be roan-colored, with a mix of red and white hairs. In humans, one of the most widely-known examples of codominance is ABO blood type. Jump to: navigation, search Binomial name Bos taurus Linnaeus, 1758 Cattle (called cows in vernacular usage) are domesticated ungulates, a member of the subfamily Bovinae of the family Bovidae. ... Roan is a type of coat color in horses (and, occasionally, in other animals, such as dogs or cattle) that is a mixture of white hairs with a base coat of another color. ... Jump to: navigation, search Binomial name Homo sapiens Linnaeus, 1758 Subspecies Homo sapiens idaltu (extinct) Homo sapiens sapiens For other uses, see Human (disambiguation). ... A blood type is a description of an individuals characteristics of red blood cells due to substances (carbohydrates and proteins) on the cell membrane. ...

Codominant traits are expressed with a capital letter and a superscript: C^RC^H. Majuscules or capital letters (in the Roman alphabet: A, B, C, ...) are one type of case in a writing system. ... A superscript is a number, figure, or symbol that appears above the normal line of type, at the right or left of another symbol or text. ...
