Because both factors are present; when we talk about blood types, we have 2 individuals with 2 different blood types and they become codominant within the reproduction; meaning, there is a set of alleles and both of them show in the phenotype.
codominance and multiple alleles
ABO blood types are controlled by codominance and multiple alleles.
blood type is an examples of multiple-allele inheritance.
The colour of wheat seeds, or skin colour are common examples used in text books.
The form of inheritance in which two (different) alleles are both expressed is called codominance. An example of codominance is the orange and black coat of a type of calico cat called a tortoiseshell. Both the orange allele and the black allele for coat color are expressed.
codominance and multiple alleles
It is called codominance or incomplete dominance.
Mendelian inheritance, incomplete dominance, codominance, multiple alleles, polygenic inheritance, and sex-linked inheritance.
ABO blood types are controlled by codominance and multiple alleles.
codominance
They have codominance.
codominance
Incomplete dominance
codominance
you mean phenotype, and its dominant alleles
blood type is an examples of multiple-allele inheritance.
the scientific terms used to describe when neither alleles are dominant nor recessive is codominance
