Klinefelter syndrome

Vedclass · Answer

(C) In $Klinefelter$ syndrome,the individual has an extra sex chromosome,resulting in a genotype of $47, XXY$. $Turner$ syndrome is characterized by the loss of an $X$ chromosome $(45, XO)$. $Down$ syndrome is caused by an extra copy of chromosome $21$ (autosome),not a sex chromosome. $Thalassemia$ is an autosomal recessive blood disorder,not a chromosomal abnormality involving extra sex chromosomes. Therefore,the correct answer is $Klinefelter$ syndrome.

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 $(2n+1)$
