Question

insertion
deletion
nondisjunction
inversion
duplication
translocation

Explanation:

Inversion is a chromosomal mutation where a segment of a chromosome is reversed end - to - end. In the given diagram, a part of the chromosome has been flipped (the order of the segments within the marked region has changed orientation), which is characteristic of inversion. Insertion involves adding a new segment, deletion is the loss of a segment, nondisjunction is related to improper separation of chromosomes during cell division, duplication is having an extra copy of a segment, and translocation is the transfer of a segment to a non - homologous chromosome.

Answer:

inversion
