Vedclass · Answer

(A) The correct matches are as follows:$(P)$ Turner syndrome: It is caused by the absence of one $X$ chromosome, resulting in a $45$ $(XO)$ genotype. This is represented as sex chromosome $(2n-1)$. Thus, $P-i$.$(Q)$ Down syndrome: It is caused by an extra copy of chromosome $21$, which is an autosome. This is represented as autosomal $(2n+1)$. Thus, $Q-iii$.$(R)$ Klinefelter syndrome: It is caused by the presence of an extra $X$ chromosome in males, resulting in a $47$ $(XXY)$ genotype. This is represented as sex chromosome $(2n+1)$. Thus, $R-ii$.Therefore, the correct sequence is $P-i, Q-iii, R-ii$.

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 $(2n+1)$

Match Column $-I$ with Column $-II$ and select the correct option.
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 $(2n+1)$
