Vedclass · Answer

(A) The chromosomal abnormalities are matched as follows:$(1)$ Patau's syndrome is caused by trisomy of the $13^{th}$ chromosome ($46 + 1 = 47$,Chromosome $13^{th}$),which corresponds to $(C)$.$(2)$ Klinefelter's syndrome is characterized by an extra $X$ chromosome in males $(44 + XXY = 47)$,which corresponds to $(A)$.$(3)$ Down's syndrome is caused by trisomy of the $21^{st}$ chromosome ($46 + 1 = 47$,Chromosome $21^{st}$),which corresponds to $(D)$.$(4)$ Turner's syndrome is characterized by the loss of an $X$ chromosome in females $(44 + X = 45)$,which corresponds to $(B)$.Therefore,the correct matching is $1-C, 2-A, 3-D, 4-B$.

List-$I$ (Syndrome)	List-$II$ (Chromosomal abnormality)
$(1)$ Patau's syndrome	$(A)$ $44 + XXY = 47$
$(2)$ Klinefelter's syndrome	$(B)$ $44 + X = 45$
$(3)$ Down's syndrome	$(C)$ $46 + 1 = 47$,Chromosome $13^{th}$
$(4)$ Turner's syndrome	$(D)$ $46 + 1 = 47$,Chromosome $21^{st}$

Column $-I$	Column $-II$
$(P)$ Turner syndrome	$(i)$ Sex chromosome $(2n-1)$
$(Q)$ Down syndrome	$(ii)$ Sex chromosome $(2n+1)$
$(R)$ Klinefelter syndrome	$(iii)$ Autosomal $(2n+1)$
