Question

Gene frequency in a population remains stable, unless and until there is ___________.

• A. Random drift
• B. Random mating
• C. Selection
• D. Mutation

Answer 1

The correct option is D Mutation

• In biology, a mutation is the alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA.
• Mutations result from errors during DNA replication or other types of damage to DNA such as may be caused by exposure to radiation or carcinogens.
• Hence, gene frequency in a population remains stable, unless and until there is a mutation.
• So, the correct answer is 'Mutation'.
