In the context of modern evolutionary synthesis, which process primarily introduces genetic variation? A) Gene flow B) Genetic drift C) Natural selection D) Sexual reproduction
Understand the Problem
The question is asking us to identify the process that primarily introduces genetic variation within the framework of modern evolutionary synthesis. We will analyze the provided options to determine which one is the most relevant.
Answer
Gene flow
The final answer is Gene flow
Answer for screen readers
The final answer is Gene flow
More Information
Gene flow is a key mechanism for introducing new genetic material into a population. It occurs when genetic material moves between populations, often through migration, and introduces variation that can lead to evolutionary change.
Tips
A common mistake is confusing gene flow with genetic drift or natural selection. Gene flow is about the movement of genes between populations, whereas genetic drift is random changes in allele frequencies and natural selection is about survival of the fittest.
