Question

identify the mechanism discussed below.
gene flow the transfer of genes from one population to another
natural selection drives the changes that occur in populations
a permanent change in the dna sequence of a gene
the random change in the frequency of an allele in a population
mutation
gene flow
genetic drift
natural selection

Explanation:

To identify the mechanism for "A permanent change in the DNA sequence of a gene", we analyze each option:

• Mutation is defined as a permanent change in the DNA sequence of a gene.
• Gene flow is the transfer of genes between populations (matches its given description, not this one).
• Genetic drift is random change in allele frequency (matches the other description, not this).
• Natural selection drives population changes (matches its given description, not this). So the correct mechanism is mutation.

Answer:

mutation
