which one of the following is a hereditary disease
The most commonly asked correct example of a hereditary disease in these exam-style questions is haemophilia (also spelled hemophilia).
Direct Answer
If the options include haemophilia , colour blindness , or sickle cell anaemia , all of these are hereditary diseases, but:
- Many competitive exams specifically mark haemophilia as the correct answer when the question is phrased as:
“Which one of the following is a hereditary disease?”
So, in that standard MCQ context, the expected answer is:
Haemophilia – a hereditary (genetic) bleeding disorder passed through X‑linked genes.
Quick Scoop: What is a Hereditary Disease?
- A hereditary disease is caused by genes passed from parents to children through their DNA.
- These conditions are present because of mutations or defects in specific genes or chromosomes , and can run in families across generations.
Common examples of hereditary diseases include:
- Haemophilia (blood clotting disorder).
- Sickle cell disease (abnormal, sickle-shaped red blood cells).
- Cystic fibrosis (affects lungs and digestive system).
- Huntington’s disease (neurodegenerative brain disease).
- Tay–Sachs disease (severe nervous system disorder in infants).
Mini Table: Examples of Hereditary Diseases
| Disease | Main Body System Affected | Hereditary Pattern (simplified) |
|---|---|---|
| Haemophilia | Blood clotting | X‑linked (more common in males) | [7][4]
| Sickle cell disease | Blood, heart, lungs, kidneys | Autosomal recessive (both parents pass the gene) | [1][3]
| Cystic fibrosis | Lungs and digestive system | Autosomal recessive | [3][1]
| Huntington’s disease | Brain and nervous system | Autosomal dominant (one copy of gene is enough) | [7][3]
| Tay–Sachs disease | Nervous system | Autosomal recessive | [9][1][3]
Forum-Style Note
In many exam prep discussions, whenever someone asks “Which one of the following is a hereditary disease?” , the go‑to key answer is haemophilia , unless the question or options specify otherwise.
TL;DR
- Haemophilia is the standard textbook/exam answer to “which one of the following is a hereditary disease?”
- Other classic hereditary diseases include sickle cell disease, cystic fibrosis, Huntington’s disease, and Tay–Sachs disease.
