The phenotypic ratio would be 3 to 1
Codominance occurs when both alleles contribute to the phenotype of a heterozygous individual. This results in a phenotype that displays characteristics of both alleles simultaneously, rather than blending them. This can lead to unique patterns or color combinations in the phenotype.
In codominance, there are at least two alleles contributing to the phenotype of an individual, each allele independently expressed. This means that both alleles are fully expressed in the heterozygous genotype, resulting in a distinct phenotype.
In a heterozygous genotype, where an individual possesses two different alleles for a particular gene, the phenotype can be influenced by the dominance relationship between the alleles. Typically, the dominant allele will mask the expression of the recessive allele, resulting in the phenotype reflecting only the dominant trait. However, in some cases, such as incomplete dominance or codominance, both alleles can contribute to the phenotype. Therefore, it is not accurate to say that both alleles always show in the phenotype.
When both alleles of a gene are different, the individual is termed heterozygous for that gene. This means that one allele is inherited from each parent, resulting in genetic variation. Heterozygous individuals can exhibit a dominant phenotype if one allele is dominant over the other, or they may show a blending of traits if both alleles contribute to the phenotype.
This is known as codominance, where both alleles in a heterozygous individual are expressed equally and simultaneously, resulting in a unique phenotype that shows characteristics of both alleles.

The dominant allele is the one that determines the phenotype in a heterozygous individual.
Homozygous dominant and heterozygous both are a dominant phenotype.
Phenotype
Heterozygous in biology refers to an individual having two different alleles for a particular gene. This means that one allele is dominant over the other, resulting in a dominant phenotype. Heterozygous individuals display a combination of traits from both alleles.
The phenotype (as I assume would be colour) for both homozygous and heterozygous yellow-grained corn is yellow.
In codominance, there are at least two alleles contributing to the phenotype of an individual, each allele independently expressed. This means that both alleles are fully expressed in the heterozygous genotype, resulting in a distinct phenotype.

Incomplete dominance and codominance are both types of genetic inheritance where neither allele is completely dominant over the other. In incomplete dominance, the heterozygous individual shows a blending of the two alleles, resulting in an intermediate phenotype. In codominance, both alleles are expressed fully in the heterozygous individual, leading to a phenotype that shows traits from both alleles distinctly.
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is homozygous recessive. A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance would probably result in a phenotype ratio is 3 dominant 1 recessive.
Codominance is a genetic trait where two different alleles for a gene are both expressed equally in the phenotype of a heterozygote individual. This results in a phenotype that shows characteristics of both alleles instead of a blending of traits. An example is the AB blood type in humans, where both A and B alleles are expressed equally.
