Correct answer: Law of Co-dominance
Co-dominance refers to the genetic scenario, in which none of the alleles is dominant or recessive, in such a situation both the allele get expressed equally, this is called as co-dominance.
Example: ABO blood group.
The blood group of the individual can be A, B, O or AB. The letter A, B, O, AB refers to the type of protein present in the blood.
If a person posses type A or type B blood group, it shows that they have dominant A or B allele present in the blood. If a person has Type O blood group, it shows neither type A or Type B allele is dominant. If a person posses type AB blood group, it means both type A and type B allele is equally expressed and are said to be co-dominant.
