Detailed explanation-1: -An inversion mutation is one type of mutation. Inversion mutations occur when a section of DNA breaks away from a chromosome during the reproductive process and then reattaches to the chromosome in reversed order. This changes the genetic code and can make it more difficult to read.
Detailed explanation-2: -Answer and Explanation: A chromosome’s gene sequence that was ABCDEFG before damage and ABCFG afterward is an example of: c) deletion.
Detailed explanation-3: -An inversion occurs when a chromosome breaks at two points and the segment bounded by the breakpoints is reinserted in the reversed orientation.
Detailed explanation-4: -One of the best-characterized recurrent inversions giving rise to disease causes hemophilia A, an X-linked disorder caused by mutations in the factor VIII gene [36].
