Read the following and answer the questions 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).

Answer:

Introduction:
The given passage describes haemophilia and color blindness as sex-linked diseases. Haemophilia is characterized by the inability of the blood to clot due to the absence of the necessary clotting factors. Color blindness, on the other hand, is a condition where the eye fails to distinguish between red and green colors. In this case, Anup is color blind and is married to Soni, who does not have the disease. The question asks about the chances of their son having the disease.

Explanation:
To understand the chances of their son having the disease, we need to consider the inheritance pattern of sex-linked diseases.

Sex-linked Inheritance:
Sex-linked diseases are typically caused by mutations in genes located on the sex chromosomes, particularly the X chromosome. In humans, males have one X and one Y chromosome (XY), while females have two X chromosomes (XX). Since the disease-causing gene is located on the X chromosome, the inheritance pattern differs between males and females.

Chance of the Son having the Disease:
In this case, Anup is color blind, which means he carries the disease-causing gene on his X chromosome. Soni, being normal, does not carry this gene.

Since Anup is a male, he will pass on his Y chromosome to his son, making him unaffected by the disease. Soni, being a carrier of the normal gene, will pass on either her X chromosome with the normal gene or her X chromosome with the disease-causing gene to their son.

The son will inherit the Y chromosome from Anup and either the X chromosome with the normal gene or the X chromosome with the disease-causing gene from Soni. Therefore, the son has a 50% chance of inheriting the disease-causing gene and being color blind, and a 50% chance of inheriting the normal gene and being unaffected by the disease.

Conclusion:
Based on the above explanation, the chance that Anup and Soni's son will have the disease is 50%. Therefore, the correct answer is option 'b) 50%'.
