According to Mendelian inheritance , a dominant allele masks the expression of a recessive allele and expresses itself. The recessive trait is expressed only in homozygous condition. In some cases, under heterozygous conditions, both the dominant and recessive alleles are co-expressed. This is known as co-dominance. The resulting trait is not an intermediate of the two alleles, but it includes the phenotype of both dominant and recessive alleles.

Features of a Concept Features of a Concept Characteristics are discrete; that is, they are unitary. Genetic features have alternative forms, and each feature is inherited from one of the two parents. These are called alleles. One allele is dominant over the other allele. The dominant allele is reflected in the phenotype. Random segregation creates the gametes. The heterozygotic individuals produce gametes with an equal frequency of both alleles. Genes are unlinked; that is, different traits arise from the independent assortment.
