A Colour blindness
B Down's syndrome
C Haemophilia
D Xerophthalmia

Answer 1

Hint A genetic condition is an illness caused in part or entirely by a deviation from the usual DNA sequence. A single gene mutation, several gene mutations, a combination of gene mutations and environmental factors, or chromosome damage can all cause genetic diseases.

Complete step by step answer:
Colour Blindness: The disease is frequently inherited. Medications and some eye illnesses are also factors. Men are more affected than women. Color blindness is a condition in which you are unable to see colours normally. Color deficiency is another name for it. Color blindness is a condition in which a person is unable to distinguish between different hues. This is most common between greens and reds, but it can also happen with blues.
Down's syndrome is a genetic condition produced by extra genetic material from chromosome 21 as a result of improper cell division. Down's syndrome is characterised by a distinctive facial appearance, intellectual impairment, and developmental delays. It's possible that it's linked to thyroid or cardiac problems.
Haemophilia is a bleeding disorder caused by a genetic inability for the blood to clot properly. This can cause bleeding on its own as well as bleeding after an injury or surgery. Clotting factors are proteins found in blood that can assist stop bleeding.

Vitamin A therapy can usually reverse xerophthalmia.

So, the correct answer is option A.

Note: Many genetic illnesses are caused by gene alterations that can be found in almost every cell in the body. As a result, these ailments frequently impact many physiological systems, and the majority of them are incurable. Some of the accompanying signs and symptoms, on the other hand, may be treatable or manageable.
