Explanation

Chromosomal aberrations are abnormalities in the structure or number of chromosomes in a cell. These can occur due to errors during cell division or exposure to certain chemicals or radiation. Examples of chromosomal aberrations include deletions (loss of a portion of a chromosome), duplications (extra copies of a portion of a chromosome), inversions (reversal of a portion of a chromosome), and translocations (movement of a portion of one chromosome to another chromosome). Chromosomal aberrations can lead to genetic disorders, birth defects, or cancer.
