Human Genetics and Disorders Questions

Multiple choice

What is the name of the genetic disease that affects the nervous system and leads to progressive loss of mental and physical abilities?

  1. Cystic fibrosis

  2. Sickle cell anemia

  3. Down syndrome

  4. Tay-Sachs disease
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Tay-Sachs disease is a genetic disorder that affects the nervous system. It is caused by a mutation in the HEXA gene, which leads to the accumulation of a fatty substance called ganglioside GM2 in the brain. This accumulation can cause progressive loss of mental and physical abilities.

Multiple choice

Which of the following is a genetic disease that affects the muscles?

  1. Cystic fibrosis

  2. Sickle cell anemia

  3. Down syndrome

  4. Muscular dystrophy
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Muscular dystrophy is a group of genetic diseases that affect the muscles. It is caused by mutations in genes that encode proteins that are essential for muscle function. These mutations can lead to progressive muscle weakness and degeneration.

Multiple choice

What is the name of the genetic disease that affects the digestive system and leads to difficulty digesting fats?

  1. Cystic fibrosis

  2. Sickle cell anemia

  3. Down syndrome

  4. Celiac disease
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Celiac disease is a genetic disorder that affects the digestive system. It is caused by an immune reaction to gluten, a protein found in wheat, barley, and rye. This reaction can damage the lining of the small intestine and lead to difficulty digesting fats.

Multiple choice

Which of the following is a genetic disease that affects the skin?

  1. Cystic fibrosis

  2. Sickle cell anemia

  3. Down syndrome

  4. Epidermolysis bullosa
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Epidermolysis bullosa is a group of genetic diseases that affect the skin. It is caused by mutations in genes that encode proteins that are essential for the structure and function of the skin. These mutations can lead to blisters, sores, and other skin problems.

Multiple choice

What is the name of the genetic disease that affects the eyes and leads to progressive loss of vision?

  1. Cystic fibrosis

  2. Sickle cell anemia

  3. Down syndrome

  4. Retinitis pigmentosa
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Retinitis pigmentosa is a group of genetic diseases that affect the eyes. It is caused by mutations in genes that encode proteins that are essential for the function of the retina, the light-sensitive tissue at the back of the eye. These mutations can lead to progressive loss of vision.

Multiple choice

Which of the following is a genetic disease that affects the heart?

  1. Cystic fibrosis

  2. Sickle cell anemia

  3. Down syndrome

  4. Congenital heart disease
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Congenital heart disease is a group of birth defects that affect the heart. It is caused by mutations in genes that encode proteins that are essential for the development of the heart. These mutations can lead to a variety of heart problems, including holes in the heart, narrowed blood vessels, and abnormal heart rhythms.

Multiple choice

What is the name of the genetic disease that affects the kidneys and leads to kidney failure?

  1. Cystic fibrosis

  2. Sickle cell anemia

  3. Down syndrome

  4. Polycystic kidney disease
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Polycystic kidney disease is a genetic disorder that affects the kidneys. It is caused by mutations in genes that encode proteins that are essential for the development and function of the kidneys. These mutations can lead to the formation of cysts in the kidneys, which can interfere with kidney function and eventually lead to kidney failure.

Multiple choice

Which of the following is a genetic disease that affects the liver?

  1. Cystic fibrosis

  2. Sickle cell anemia

  3. Down syndrome

  4. Hemochromatosis
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Hemochromatosis is a genetic disorder that affects the liver. It is caused by mutations in genes that encode proteins that are involved in iron metabolism. These mutations can lead to the accumulation of iron in the liver, which can damage the liver and lead to liver failure.

Multiple choice

What is the name of the genetic disease that affects the immune system and leads to recurrent infections?

  1. Cystic fibrosis

  2. Sickle cell anemia

  3. Down syndrome

  4. Severe combined immunodeficiency
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Severe combined immunodeficiency (SCID) is a genetic disorder that affects the immune system. It is caused by mutations in genes that encode proteins that are essential for the development and function of the immune system. These mutations can lead to recurrent infections, which can be life-threatening.

Multiple choice

Which of the following is a genetic disease that affects the endocrine system and leads to diabetes?

  1. Cystic fibrosis

  2. Sickle cell anemia

  3. Down syndrome

  4. Type 1 diabetes
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Type 1 diabetes is a genetic disorder that affects the endocrine system. It is caused by mutations in genes that encode proteins that are essential for the production of insulin, a hormone that regulates blood sugar levels. These mutations can lead to the destruction of insulin-producing cells in the pancreas, which can result in diabetes.

Multiple choice

What is the name of the genetic disease that affects the nervous system and leads to seizures?

  1. Cystic fibrosis

  2. Sickle cell anemia

  3. Down syndrome

  4. Epilepsy
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Epilepsy is a group of genetic disorders that affect the nervous system. It is caused by mutations in genes that encode proteins that are essential for the function of the brain. These mutations can lead to seizures, which are sudden bursts of electrical activity in the brain that can cause a variety of symptoms, including loss of consciousness, convulsions, and muscle spasms.

Multiple choice
