Which of the following best defines gene flow?

Step 1: Define the Problem

Identify the key components of the question that need to be addressed: The question asks for the definition of "gene flow."

Step 2: Break Down the Problem

Divide the problem into smaller, manageable parts:

• Understand what gene flow is.
• Identify the characteristics that define gene flow.

Step 3: Apply Relevant Concepts

Use appropriate academic theories or formulas to solve each part of the problem:

• Gene flow refers to the transfer of genetic material from one population to another. It occurs when individuals from different populations interbreed, resulting in the exchange of genes.

Step 4: Analysis, Verify and Summarize

Analysis each part in details if necessary carry out the calculations by steps. Verify the calculations result and summarize the findings:

• Gene flow is an important mechanism in evolution as it can introduce new genetic variations into a population, potentially affecting allele frequencies and increasing genetic diversity.

Final Answer

Gene flow is best defined as the transfer of genetic material between separate populations, often through migration and interbreeding, which can lead to changes in allele frequencies within a population.
