In hexaploid wheat, what are the haploid $(n)$ and basic $(x)$ chromosome numbers?

$Statement A$: For a particular character in an individual,each gamete gets only one allele.
$Statement B$: Chromatids of a chromosome split (separate) and move towards opposite poles during anaphase of mitosis.

$ABO$ blood type in man is an example of
$A$. Pleiotropy
$B$. Incomplete dominance
$C$. Co-dominance
$D$. Multiple allelism
Select the code for the correct answer from the options given below.

Match the terms in Column $I$ with its phenotypic ratio in Column $II$ correctly and choose the correct option.

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	$d$. $9:3:3:1$

Match the following columns correctly:

Column-$I$	Column-$II$
$(a)$ $1 : 2 : 1$	$(i)$ Test cross
$(b)$ $3 : 1$	$(ii)$ Law of Dominance
$(c)$ $9 : 3 : 3 : 1$	$(iii)$ Incomplete Dominance
$(d)$ $1 : 1 : 1 : 1$	$(iv)$ Law of Independent Assortment
	$(v)$ Law of Segregation

$A$ : Test cross is the tool for knowing linkage between genes.
$R$ : Monohybrid test cross gives two phenotypes and two genotypes.
