Question

Deletion of certain genes cause

• A. Gene mutation
• B. Chromosome mutation
• C. Gene modification
• D. Aneuploidy

Answer 1

Answer: (B)

Chromosome mutation

A mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. The gene is the basic physical and functional unit of heredity. It consists of a specific sequence of nucleotides at a given position on a given chromosome that codes for a specific protein. Deletion of certain genes causes chromosome mutation because genes are a sequence of nucleotides at a given position on a given chromosome.

So, the correct answer is 'Chromosome mutation'.
