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.

The DNA or deoxyribonucleic acid is the carrier of genetic information from all forms of living organisms. This is the main reason of the inheritance of traits, behaviors, attitude, physical appearances, and many more that helped, not just the human being, but all living organisms in the planet to adapt, adjust, evolve, and survive for generations and generations. The DNA is carried by the cells of the living organisms' body and is stored and shared eventually. Though it was discovered that the DNA is a long complicated helix that contains mostly all the information of life, this is stored in the nucleus of a cell because it is folded and condensed together with the other genetic materials.
