The correct answer is:
Codominance
Codominance
The example of codominance is ABO blood grouping in humans. $\mathrm{ABO}$ blood groups are controlled by gene I. Gene I consists three alleles IA, IB and IA and IB are the dominant alleles. When IA and IB are present together, both express equally and produce the surface antigens $\mathrm{A}$ and $\mathrm{B}$, whereas $\mathrm{i}$ is the recessive allele and does not produce any antigen.
The genetic effect of a single gene on multiple phenotypic traits is pleiotropy. Incomplete dominance a genetic term in which does not completely dominate another allele.
The separation of allele during the process of gametogenesis is known as Segregation. This is the basis of reappearance of recessive character in $\mathrm{F}_2$-generation.
