Co-dominance happens when two genotypes are expressed at the same time. For example, one parent can have blood type A and one parent can have blood type B and together produce a child with blood type AB. If two parents have the blood type AB, the child has a chance of being mentally ill.
it is incomplete dominance because it runs in the genes

Incomplete Dominance
When both the alleles are expressed, it is called co-dominance or mixed dominance.
When each allele has its own degree of influence it is known as incomplete dominance.
If neither are Dominant Or Recessive then its called co dominance or spuedo - dominance
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.
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.
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:
