Incomplete dominance is when both the dominant gene and recessive gene are present in an organism's phenotype. For example, since brown eyes are dominant and blue eyes are recessive in humans, a person who has incomplete dominance of eye color would have gray or green eyes; a mixture of both brown and blue.
Codominance is when two dominant alleles are present at the same time.
These two terms are not the same!
it is incomplete dominance because it runs in the genes
Incomplete Dominance
When each allele has its own degree of influence it is known as incomplete dominance.
complete dominance incomplete dominance co-dominance multiple alleles polygenic inheritance
This is called co-dominance. Both alleles are expressed. For example, if white and red in a flower are co-dominant, the offspring will have both red and white petals in a flower. See link below:
Incomplete dominance and co-dominance differ from typical Mendelian crosses in that they involve more complex inheritance patterns. In incomplete dominance, the heterozygous phenotype is a blend of the two homozygous phenotypes, while in co-dominance, both alleles are expressed fully in the heterozygous individual. This contrasts with typical Mendelian crosses where one allele is dominant and masks the expression of the other recessive allele.
Both co-dominance and incomplete dominance involve a situation where alleles do not follow the traditional dominant-recessive pattern of inheritance. In both cases, heterozygous individuals show a phenotype that is a blend of the two homozygous phenotypes. The main difference is that in co-dominance, both alleles are fully expressed, while in incomplete dominance, the phenotype is a mix of the two alleles.
Both alleles are expressed in offspring when neither allele is dominant over the other, resulting in co-dominance. This means that both alleles are simultaneously expressed in the offspring's phenotype.
When genes are neither recessive nor dominant, they are said to exhibit incomplete dominance or co-dominance. In incomplete dominance, both alleles are expressed in the phenotype, resulting in a blending of traits. In co-dominance, both alleles are fully expressed in the phenotype, leading to a combination of traits.
