Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is it called when neither allele is dominant and two traits are blended?
A
Co-dominance
B
Incomplete Dominance
C
Pedigree
D
Sex-linked
Explanation: 

Detailed explanation-1: -Incomplete dominance is a form of Gene interaction in which both alleles of a gene at a locus are partially expressed, often resulting in an intermediate or different phenotype. It is also known as partial dominance.

Detailed explanation-2: -Codominance occurs when the alleles do not show any dominant and recessive allele relationship. However, each allele from homozygote is able to add phenotypic expressions in the offspring or simply the “mix” of each allele.

Detailed explanation-3: -Codominance Definition Codominance is a form of inheritance wherein the alleles of a gene pair in a heterozygote are fully expressed. As a result, the phenotype of the offspring is a combination of the phenotype of the parents. Thus, the trait is neither dominant nor recessive.

Detailed explanation-4: -Abstract. Incomplete dominance results from a cross in which each parental contribution is genetically unique and gives rise to progeny whose phenotype is intermediate. Incomplete dominance is also referred to as semi-dominance and partial dominance.
