Vedclass · Answer

(B) $ABO$ blood grouping in humans is controlled by three alleles: $I^A, I^B,$ and $i$. Since there are more than two alleles involved,it is an example of multiple allelism.Statement $I$ is correct.When both $I^A$ and $I^B$ are present together,they both express themselves equally,resulting in the $AB$ blood type. This phenomenon is known as codominance.Statement $II$ is correct.Codominance is phenotypically manifested in humans because individuals with the $AB$ blood type express both $A$ and $B$ antigens on the surface of their red blood cells,which can be detected through blood testing.Statement $III$ is correct.$ABO$ blood grouping does not follow Mendel's law of independent assortment in the context of multiple alleles,though it follows segregation. However,in the context of standard biology questions,statements $I, II,$ and $III$ are the most accurate descriptions of the system.

Column $I$	Column $II$
$i$. Monohybrid test cross	$a$. $1:2:1$
$ii$. Incomplete dominance	$b$. $1:2$
$iii$. Law of independent Assortment	$c$. $1:1$
$iv$. Sickle Cell Anaemia	$d$. $9:3:3:1$
