What is meant by a mutant gene being codominant?
A mutant gene that is expressed phenotypically in both heterozygous and homozygous individuals. The phenotype is not the same in heterozygous and homozygous individuals because both genes are expressed in some degree in heterozygous individuals. The phenotype may be intermediate between the two homozygous phenotypes, or sensitive tests may detect each gene’s product. ‘Codominant’ has many synonyms, such as incomplete dominant, partial dominant, semidominant, transdominant, less than dominant, and others. 5. Move genotype and phenotype to follow the definition of gene. At present, ‘phenotype’ is used in the fourth definition.
