Vedclass · Answer

(C) The gene '$I$' controls the $ABO$ blood grouping and exists in three allelic forms: $I^A$,$I^B$,and $i$.Since humans are diploid organisms,each individual possesses only two of these three alleles.The alleles $I^A$ and $I^B$ produce different types of sugar polymers on the surface of red blood cells,whereas the allele '$i$' does not produce any sugar.Therefore,the statement that $I^A$ and $I^B$ express the same type of sugar is incorrect,as they are codominant and produce different sugars.
