Question

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

Explanation:

• Mutation is defined as a permanent change in a gene's DNA sequence.
• Gene flow is the transfer of genes between populations.
• Genetic drift is random allele frequency change in a population.
• Natural selection is the driver of population changes via trait fitness.

Match each definition to the correct term:

1. "The transfer of genes from one population to another" → gene flow
2. "Drives the changes that occur in populations" → natural selection
3. "A permanent change in the DNA sequence of a gene" → mutation
4. "The random change in the frequency of an allele in a population" → genetic drift

Answer:

• "The transfer of genes from one population to another" → gene flow
• "Drives the changes that occur in populations" → natural selection
• "A permanent change in the DNA sequence of a gene" → mutation
• "The random change in the frequency of an allele in a population" → genetic drift
