A hereditary blood disease causing suppressed hemoglobin production is?

The correct answer is Thalassemia.

Thalassemia is a hereditary blood disorder caused by mutations in the genes that control the production of hemoglobin. Hemoglobin is the protein in red blood cells that carries oxygen throughout the body. In people with thalassemia, the body produces less hemoglobin than normal, which can lead to anemia. There are different types of thalassemia, depending on which genes are mutated. Some types of thalassemia are mild and do not require treatment, while others are more severe and can be life-threatening.
