Solution
The correct option is B
Translocation
The correct option is B.
Explanation for the correct option:
When a segment of one chromosome separates and joins another, the process is known as translocation.
This type of cell rearrangement is said to as balanced if no genetic material is added or removed.
If there is a gain or loss of genetic material, the translocation is considered to be unbalanced.
Explanation for the incorrect options:
Option A:
A chromosomal inversion is a rearrangement in which a chromosome segment is turned around the end to end.
Option C:
When chromosomes of the same kind are paired together during meiosis, a biological event called crossing over takes place.
Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up.
Option D:
A key technique by which new genetic material is produced throughout molecular evolution is gene duplication, also known as chromosomal duplication or gene amplification.
Final answer: The movement of a gene from one linkage group to another is called translocation.
