1 Down’s syndrome
2 Klienefelter’s syndrome
3 Turner’s syndrome
4 None of the above
Explanation:
Down syndrome is also known as trisomy 21. It is a genetic disorder caused due to the presence of a part of a third copy of chromosome 21

Aneuploidy is
1 Gain of chromosome
2 Loss of chromosome
3 Gain of a gene
4 Both (1) and (2)
Explanation:
Failure of segregation of chromatids during cell division cycle results in the gain or loss of a chromosome(s), called aneuploidy.

A man having Klinefelter’s syndrome is
1 Intersex with secondary sexual characters on the side of female
2 Female with secondary sexual characters of male
3 Male with secondary sexual characters of female
4 Normal fertile male
Explanation:
Klinefelter syndrome is a chromosomal disorder, also known as 47, XXY or XXY. This condition result from two or more X chromosomes in males. Such individuals are counted as males phenotypically, but they can exhibit some female secondary characters (breast growth, less body hair)and are commonly sterile.

The genotype of a boy having sexual characters of a girl is
1 XYY
2 XO
3 XXXY
4 XXY
Explanation:
The genotype of a boy carrying sexual characters of a girl is seen in Klinefelter’s syndrome having XXY genotype. In this syndrome, the males exhibit some secondary sexual traits of females and are generally sterile
