You are counseling a young Greek couple because both parents and their first-born son have been tested and found to be carriers of Beta thalassemia, an autosomal recessive severe hemoglobinopathy. They wish to know whether a current pregnancy is likely affected. Explain

Beta thalassemia is an autosomal recessive disorder. It is usually inherited by children if both parents are carriers. It is a blood disorder that is characterized by decreased production of hemoglobin. Hemoglobin is an important protein in red blood cells that binds oxygen to be transported to other cells in the body.

Pregnant women with beta thalassemia can develop anemia due to the stress and other underlying factors. This can increase the chances of premature delivery. She may need more frequent blood transfusions during the pregnancy period for her health and the health of the baby.

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

hope this
