Detailed explanation-1: -(in-VER-zhun) A chromosomal defect in which a segment of the chromosome breaks off and reattaches in the reverse direction.
Detailed explanation-2: -One well known example of an inversion mutation in humans is hemophilia, a disease that inhibits the ability of blood to clot. Researchers discovered the gene responsible for hemophilia years ago, but also found that DNA from a person with hemophilia had the same genetic makeup as a person without the disease.
Detailed explanation-3: -Answer and Explanation: A chromosome’s gene sequence that was ABCDEFG before damage and ABCFG afterward is an example of: c) deletion.
Detailed explanation-4: -There are two types of inversion, paracentric and pericentric, with the difference being whether the centromere is involved in the rearrangement. A pericentric inversion includes the centromere in the inverted segment, while a paracentric inversion does not.
