Question

Genetic variation in a population arises due to :

• A. Mutations as well as recombination
• B. Reproductive isolation and selection
• C. Mutations only
• D. Recombination only

Answer 1

The correct option is A Mutations as well as recombination

• Genetic variation is the difference in genome between individuals within a population.
  
• Mutation is the permanent change in the sequence of DNA. It results in difference arising at the genetic level which might be beneficial, harmful or neutral.
• Recombination involves the exchange of genetic material between homologous chromosomes. This results in shuffling of genes creating new combinations of variants in offspring.
• So, the correct answer is 'Mutations as well as recombination'
