Answer:

Deletion

Explanation:

Deletion is a type of chromosomal mutations wherein one or more genes are lost from the chromosomes. The deletion occurs when part of the chromosome is detached from the chromosome. According to the question, the part of chromosome 20 is lost as the broken segment did not rejoin the chromosome. Hence, it is a deletion mutation.
