What is the main cause of sickle cell anemia?
What is the main cause of sickle cell anemia?
- Structural abnormalities in the hemoglobin chains (correct)
- Overproduction of abnormal hemoglobin chains
- Lack of hemoglobin in the red blood cells
- Decreased production of normal hemoglobin chains
What is the difference between hemoglobinopathies and thalassemias?
What is the difference between hemoglobinopathies and thalassemias?
- Hemoglobinopathies involve normal production but decreased amount of hemoglobin chains, while thalassemias involve abnormal production of hemoglobin chains
- Hemoglobinopathies and thalassemias both involve abnormal production of hemoglobin chains
- Hemoglobinopathies involve abnormal production of hemoglobin chains, while thalassemias involve normal production but decreased amount of hemoglobin chains (correct)
- Hemoglobinopathies and thalassemias both involve normal production but decreased amount of hemoglobin chains
What is the difference between heterozygous and homozygous inheritance of abnormal genes for hemoglobin production?
What is the difference between heterozygous and homozygous inheritance of abnormal genes for hemoglobin production?
- Heterozygous inheritance leads to abnormal hemoglobin production, while homozygous inheritance leads to normal hemoglobin production
- Heterozygous inheritance leads to increased production of abnormal hemoglobin, while homozygous inheritance leads to decreased production of abnormal hemoglobin
- Heterozygous inheritance leads to normal hemoglobin production, while homozygous inheritance leads to abnormal hemoglobin production (correct)
- Heterozygous inheritance leads to decreased production of abnormal hemoglobin, while homozygous inheritance leads to increased production of abnormal hemoglobin
