Different types of dominance in genes

An example of a simple phenotype, is flower color in Mendel’s peas. We have already said that one allele as a homozygote produces purple flowers, while the other allele as a homozygote produces white flowers. But what about a heterozygous individual that has one purple allele and one white allele? What is the … See more Other than the complete dominant and recessive relationship, other relationships can exist between alleles. In incomplete dominance (also called semi-dominance), both alleles affect the trait additively, and the phenotype of the … See more Co-dominance is another type of allelic relationship in which a heterozygous individual expresses the phenotype of both alleles simultaneously.
