Vedclass · Answer

(A) The condition where sex chromosomes fail to separate during meiosis is known as non-disjunction.$(a)$ The genotype $22$ pairs $+ XXY$ represents Klinefelter syndrome,which occurs in males.This condition arises due to the fertilization of an abnormal ovum containing $22 + XX$ chromosomes by a normal sperm containing $22 + Y$ chromosomes,or by the fertilization of a normal ovum by an abnormal sperm containing $22 + XY$ chromosomes.Therefore,$22$ pairs $+ XXY$ is a correct genotype for a male phenotype.

List-$I$	List-$II$
$A.$ Down's syndrome	$I.$ $11^{th}$ chromosome
$B.$ $\alpha$-Thalassemia	$II.$ $X$ chromosome
$C.$ $\beta$-Thalassemia	$III.$ $21^{st}$ chromosome
$D.$ Klinefelter's syndrome	$IV.$ $16^{th}$ chromosome

In humans,sometimes during gametogenesis,sex chromosomes do not separate,resulting in a chromosome number of $45$,$47$,or $48$. In this condition,which of the following genotype and phenotype combinations is correct?
