This is incorrect.(iii) $I^A$ produces $N$-acetylgalactosamine,while $I^B$ produces galactose. They produce different sugars. This is incorrect.(iv) The allele $i$ does not produce any sugar,whereas $I^A$ and $I^B$ produce specific sugars. This is incorrect.$(v)$ $I^A$ and $I^B$ are codominant,not incompletely dominant. This is incorrect.Therefore,statements $(ii), (iii), (iv),$ and $(v)$ are incorrect.
