Which of the following is NOT a term used to describe a process that results in abnormal chromosomal structure?

A. Duplication

B. Freezing

C. Translocation

D. Deletion

B. Freezing

Explanation:

Duplication, translocation and deletion are phenomenons that result in unusual rearrangement of chromosomes. Those phenomenos change the structure of chromosomes and can cause problems in the development and function of the organism's systems.

Translocation is the binding of a chromosome fragment to a chromosome to which it did not initially belong.

Deletion is the loss of a chromosome fragment, which does not necessarily bind to another chromosome.

Duplication is the duplication of a chromosome fragment that generates two identical segments on the same chromosome.
