Question

Alleles for gene I are $I^A,I^B$ and $I^O$. If $I^A$ and $I^B$ are dominant over $I^O$, the $I^A=I^B>I^O$ indicates _____________.

• A. Codominance
• B. Recessive
• C. Weiner hypothesis
• D. Dominance.

Answer 1

The correct option is A Codominance

A.Codominance - Expression of phenotypes of both parents in heterozygous condition is called codomiance.

B.Recessive – In heterozygous organisms, in the pair of contrasting characters or traits, the trait, which is not expressed is called Recessive trait.

C.Weiner hypothesis – He proposed, Rh system of blood groups. He found that human RBCs were agglutinated by an antibody, apparently common to all rhesus monkeys and 85% of humans. This factor was named the Rh factor.

D.Dominance - In heterozygous organisms, in the pair of contrasting characters or traits, the trait, which is expressed is called Dominance trait.

So, the correct option is ‘Codominance’.
