In man, which of the following genotypes and phenotypes may be the correct result of aneuploidy in sex chromosomes?
1 22 pairs \(+X X Y\) males
2 22 pairs +XX females
3 22 pairs + XXXY females
4 22 pairs +X females
Explanation:
: In man, 22 pairs + XXY males genotypes and phenotypes may be correct result of aneuploidy in sex chromosomes. Aneuploidy-It is the presence of a chromosome number which is different than the multiple of basic chromosome number, this type of variation involve are or two chromosomes but not the entire set. - 22 pairs + XXY is hyperploidy (types of aneuploidy) in which one or more chromosomes (individually) one added to the diploid set of chromosome. - In XXY 47 chromosome instead of 46 , it is example of trisomy \((2 n+1)\).

Which one is a sex linked disease?
1 Colour blindness
2 Haemophilia
3 Syphilis
4 Both (a) and (b)
Explanation:
: Colour blindness and haemophilia are sex linked disease. Haemophilia is a sex linked recessive disease which shows its transmission from unaffect carrier female to some of the male progeny. In this clisease a protein involved in the clotting of blood is affected due to this, in an affected individual simple cut will result in monstop bleeding. Colour blindness- A particular trait in human beings enables them to differentiate between red and green colours. The gene for this red-green colour blindness is located on X-chromosome. It is recessive to normal wision.

Which of the following is not a hereditary disease?
1 Cretinism
2 Cystic fibrosis
3 Haemophilia
4 Thalassemia
Explanation:
: Cretinism is not a hereditary disease. It is occurs due to hypothyroidism sirce birth. - Thalassaemia \(\rightarrow\) Autosonal recessive clisease. - Cystis fibrosis \(\rightarrow\) Autosomal recessive disease. - Haemophilia \(\rightarrow\) Sex-linked recessive disease.

If a haemophilic carrier female marries a normal man, the chances are that
1 all the daughters will have haemophilia
2 \(50 \%\) of the daughters will have haemophilia
3 \(50 \%\) of the sons will have haemophilia
4 all the sons will have haemophilia
Explanation:
