Alleles b and c also produce sugar.

Vedclass · Answer

(A) The wrong statement is: $A$. Alleles $b$ and $c$ also produce sugar.Explanation:$1$. The $ABO$ blood grouping in humans is controlled by the gene $I$,which has three alleles: $I^{A}$,$I^{B}$,and $i$.$2$. The alleles $I^{A}$ and $I^{B}$ produce specific enzymes (glycosyltransferases) that add sugar polymers to the surface of red blood cells,forming antigens $A$ and $B$,respectively.$3$. The allele $i$ does not produce any sugar or antigen.$4$. When $I^{A}$ and $I^{B}$ are present together,both express themselves equally,a phenomenon known as co-dominance.$5$. $I^{A}$ and $I^{B}$ are dominant over $i$,meaning if $I^{B}$ and $i$ are present,the phenotype will be blood group $B$ (due to $I^{B}$ expression).

Column-$I$	Column-$II$
$(A)$ Dominance	$(1)$ Many genes govern a single character.
$(B)$ Co-dominance	$(2)$ In a heterozygous organism, only one allele expresses itself.
$(C)$ Pleiotropy	$(3)$ In a heterozygous organism, both alleles express themselves fully.
$(D)$ Polygenic inheritance	$(4)$ $A$ single gene influences many characters.
