Vedclass · Answer

(B) The inheritance of $ABO$ blood groups in humans is governed by the gene $I$,which has three alleles: $I^A$,$I^B$,and $i$.$1$. $I^A$ and $I^B$ are dominant over $i$,showing complete dominance ($I^A > i$ and $I^B > i$).$2$. When both $I^A$ and $I^B$ are present together,they both express themselves equally,which is an example of co-dominance.$3$. Since there are three alleles $(I^A, I^B, i)$ for a single gene locus,it is an example of multiple allelism.$4$. It does not involve incomplete dominance.Therefore,the conditions involved are complete dominance $(I)$,co-dominance $(II)$,and multiple allelism $(III)$.

The inheritance of $ABO$ blood group is an example of which of the following conditions?
$I -$ Complete dominance,$\quad II -$ Co-dominance
$III -$ Multiple allelism,$\quad IV -$ Incomplete dominance
