Klinefelter's syndrome - $44$ autosomes $+ XXY$

Vedclass · Answer

(A) $1$. Klinefelter's syndrome is a genetic disorder caused by an extra $X$ chromosome in males,resulting in a karyotype of $44$ autosomes $+ XXY$ ($47$ chromosomes).$2$. Color blindness is an $X$-linked recessive disorder,not $Y$-linked.$3$. Erythroblastosis fetalis is caused by $Rh$ incompatibility between the mother and the fetus,not by $X$-linked inheritance.$4$. Down's syndrome is caused by trisomy of chromosome $21$,resulting in $45$ autosomes $+ XX$ or $XY$ ($47$ chromosomes total),not $44$ autosomes $+ X0$ (which is Turner's syndrome).Therefore,the correct match is Klinefelter's syndrome.

Column $I$	Column $II$
$(A)$ Aneuploidy	$(i)$ Increase in whole set of chromosomes
$(B)$ Monoploidy	$(ii)$ Loss or gain of a chromosome
$(C)$ Polyploidy	$(iii)$ Two sets of chromosomes
$(D)$ Diploidy	$(iv)$ $A$ single set of chromosomes
