Answer:
Sickle cell anemia is an inherited condition in which there aren't enough healthy red blood cells to carry oxygen through an individual's body. The red blood cells of a healthy individual are flexible and round, and they move through blood vessels with no problem, transporting oxygen successfully. However, a person with sickle cell anemia has rigid, sticky red blood shaped like sickles or crescent moons. These cells often get stuck in small blood vessels, which can slow or block blood flow and oxygen delivery to different parts of the body.
The sickle cell anemia trait is found on a recessive allele of the hemoglobin gene, while the regular red blood cell trait is found on the dominant allele. This means that a person must have two copies of the recessive allele (one from their mother and the other from their father) to be born with this condition. People who have one dominant and one recessive allele or both dominant alleles will have healthy red blood cells.

<h2>Mutation & genetic drift</h2>
Explanation:
- A mutation is characterized as a lasting change to the DNA succession in a quality. This change moves the hereditary message conveyed by the quality and can modify the amino corrosive arrangement of the protein the quality encodes. This implies future cells created by the quality will just convey a specific characteristic.
- Genetic Drift is the change in the hereditary structure of a populace after some time because of possibility or irregular occasions. In instances of hereditary float, for example, catastrophic events or periods of irregular climate, the age that makes due to repeat won't really be the fittest, yet the most fortunate. Hereditary float doesn't allude to a particular change in hereditary cells, rather to arbitrary events that impact a population's genetic makeup.
- Hence, the right answer of the fill up the blank is "mutation and genetic drift".
