Assertion : Person’s suffering from haemophilia fail to produce blood clotting factor VIII. Reason : Prothrombin producing platelets in such persons are found in very low concentration.
1 Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false.

Haemophillic man marries a normal woman. Their offsprings will be
1 All boys haemophillic
2 All haemophillic
3 All girls
4 All normal
Explanation:
Hemophilia is a inherited recessive sexlinked disorder i.e. , gene is located on the X chromosome. As the man is haemophilic that means he is having the defective gene on his X chromosome. And the woman is normal means she has two X chromosomes without the defective gene. Boys will inherit Y chromosome from father and the X chromosome from mother means boys will be normal. Girls will inherit one X chromosome from father and the other from mother, so they will inherit the defective X chromosome from father and a healthy chromosome from her mother but they will only be carriers. Therefore, all the offsprings will be normal.
