Dolce · Answer 1

Answer&Explanation:An individual with an autosomal dominant disorder, has a single mutant gene unless when their both parents are affected.

A person will have an autosomal dominant disorder if only a single parent is affected and if parent have autosomal dominant disorder only there is a 50% of inheriting a mutant gene.

In autosomal recessive disorders a person will get Ill if they inherit both mutant genes from both parents who are carriers. This person will be homozygous for the gene and will be affected by the disorder and this is highly likely to happen in their baby since they are both the carriers of this disorder.

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.
