The gene for haemophilia is located on ' X ' chromosome. Hence it is normally impossible for a
1 haemophilic father to pass the gene to his caughter.
2 cartier mother to pass the gene to her daughter.
3 carrier mother to pass the gene to her son.
4 hemophilic father to pass the gene to his son.
Explanation:
: A father who has hemophilia passes his only X chromosome down to all of his daughters. So they will always get his hemophilia allele and be heterozygous. A father passes down his Y chromosome to his sons thus he cantrot pass down a hemophilia allele to them. The daughter will not have hasmophilia since the normal blood clotting gene from her mother is dominam. The daughter is called a carrier for haemophilia.

A woman with normal vision, but whose father was colourblind, marries a colourblind man. Suppose that the fourth child of this couple was a boy. This boy
1 must have normal colour vision
2 will be partially colourblind since he is heterozygous for the coloublind mutant allele
3 must be colourblind
4 may be coloublind or may be of normal vision JPMER-2007
Explanation:
: A woman whose father was colour blind will be a carrier of the cisease. Sons get their \(X\) chromosome from their mother. So there are \(50 \%\) chances of son being colour blind if the mother is a carrier.

Choose the correct option for the pedigree analysis given below:
1 Autosomal dominant pedigres
2 ' X '-linked dominant pedigree
3 Autosomal recessive pedigree
4 ' X '- linked tecessive pedigree
Explanation:
: The pedigree analysis given is autosomal dominant pedigres which is represented for neurofibromatiosis autosomal trait which is also called "won Reckling hausen disease" caused by a dominant gene on chromosome 17.

Philadelphia chromosome is found in the patient suffering from
1 albinistn
2 insomia
3 myelocytic leukaemia
4 hepatitis.
Explanation:
: Chrornic Myelogenous Leukaemia (CML) is caused due to an obromal chromosome Philadelphia chromosome. Philadelphia chromosome is actually the tesult of a reciprocal translocation between chromosome 9 and 22. In the Philadelphia translocation the tip of the long arm of chromosome 9 has been joined to the body of chromosome 22 and the clistal Fortion of the long arm of chromosome 22 has been joined to the body of chromosome 9. CML is characterized by an excess of gramular lewcocytes in the tilood.
