Answer:
A genetic disorder that is inherited as a recessive trait is sickle cell anemia.
Explanation:
Sickle cell anemia can be described as a disorder which is caused by a mutation in the hemoglobin beta gene which is found on chromosome number 11. The pattern of inheritance of sickle cell anemia is autosomal recessive which means that both the alleles of the gene shall be recessive for the trait to occur. A person with one recessive allele for the trait will not carry the disease but will be a carrier for the disease.

Answer:
With regard to bone decalcification secondary to hypocalcemia, what an endocrinologist and an orthopedist have in common is that they both focus on calcium levels.
Explanation:
Endocrinology and traumatology are two different medical specialties, however they can together treat a person with a metabolic disorder affecting the bones.
In the case of a person with thyroid problems, where probably the parathyroid glands are affected, there are low levels of calcium in the blood —hypocalcemia— which affects the bones secondarily by decalcification, both the endocrinologist and the traumatologist will coincide in the treatment of the serum calcium levels:
- <u>Endocrinologist</u> will treat the hormonal problem that produces low calcium in the blood.
- <u>Orthopedist</u> will indicate a calcium replacement treatment to improve the levels of the mineral in the blood, and restore the calcium lost by the bones.
The joint treatment of both specialists can guarantee the recovery of a patient with problems in the metabolism of calcium.
Answer:
Explanation:
