Final answer:
Hemophilia A is the X-linked recessive disorder among the options. It is a blood clotting disorder carried on the X chromosome, and it is disproportionately observed in males because they have only one X chromosome.
Step-by-step explanation:
The X-linked recessive disorder among the options provided is hemophilia A. This condition is characterized by a deficiency in the blood clotting factor VIII, making it difficult for blood to clot and leading to prolonged bleeding. Hemophilia A is inherited in an X-linked recessive pattern, which means that the disorder is carried on the X chromosome. Because females have two X chromosomes, they can be carriers of X-linked recessive diseases without showing symptoms, while males, with only one X chromosome, are more likely to express the disorder if they inherit a recessive gene.
Cystic fibrosis is an example of an autosomal recessive disorder, where two copies of the faulty gene must be inherited for the disease to be expressed. Neurofibromatosis is an autosomal dominant disorder, meaning only one copy of the faulty gene needs to be inherited for the condition to present. Turner syndrome is a condition that arises from a non-inherited chromosomal abnormality. Accordingly, the other diseases mentioned are not X-linked recessive.
