Question

Changes in the frequency of occurrence of alleles in a population could be due to ___________.

• A. Mutation
• B. Random mating
• C. Migration of individuals
• D. All of these

Answer 1

The correct option is D All of these

The frequency of occurrence of a specific allele or gene in a population usually remains fixed until the population is exposed to certain changes like natural disasters, migration of individuals to a different population or random mating with individuals from another population. Gene frequencies could also get altered as a result of mutations, which are sudden heritable changes in genomes that can lead to variations.
