Reerna, Jai and Ankit are suffering from autoimmune diseases of adrenal cortex, joints and thyroid gland, respectively. Their immune system failed to recognise self and non-self and started destroying their body's own proteins.

Read the following and answer any four questions from (i) to (v) given below:
Haemophilia is a sex linked disease which is also known as bleeder's disease as the patient will continue to bleed even from a minor cut since he or she does not possess the natural phenomenon of blood clotting due to absence of anti -haemophilic globulin or factor VIII and plasma thromboplastin factor IX essential for it. As a result of continuous bleeding the patient may die of blood loss. Colour blindness is another type of sex linked trait in which the eye fails to distinguish red and green colours. Vision is however, not affected and the colour blind can, lead a normal life, reading, writing and driving (distinguishing traffic lights by their position).
  1. If a haemophilic man marries a woman whose father was haemcphihc and mother was normal then which of the following holds true for their progenies?
  1. Of the total number of daughters, 50% daughters are carrier and $50 \%$ are haemophilic.
  2. All the daughters are haemophilic.
  3. All sons are haemophilic and all daughters are normal.
  4. All sons are normal, all daughters are carriers.
  1. A man whose father was colourblind and mother was normal marries a woman whose father was haemophilic and mother was normal. Which of the following is true for their progenies? [Note: Percentage is from the total number of progenies]
  1. $25 \%$ female progenies carry the gene for both haemophilia and colourblindness.
  2. $25 \%$ male progenies carry only the gene of colourblindness.
  3. $25 \%$ female progenies carry only the gene of colourblindness.
  4. $25 \%$ male progenies and 25% female progenies carry the gene of haemophilia.
  1. Which of the following statements is incorrect regarding haemophilia?
  1. It is a dominant disease.
  2. A single protein involved in clotting of blood is affected.
  3. It is recessive disease.
