Chromosomal aberration

Vedclass · Answer

(A) change in the number of chromosomes is referred to as chromosomal aberration or chromosomal mutation. Chromosomal aberrations include changes in the number of chromosomes (aneuploidy or polyploidy) or changes in the structure of chromosomes. Gene mutation refers to changes in the $DNA$ sequence of a single gene. Somatic mutation occurs in non-reproductive cells and is not inherited. Polyploidy is a specific type of chromosomal aberration where an organism has more than two complete sets of chromosomes,but the broader term for any change in chromosome number is chromosomal aberration.
