Question: In your own words, explain why gene flow among populations reduces the potential for local adaptation within each population.

Gene flow is the movement of alleles (different forms of a gene) from one population to another. This can happen through migration, interbreeding, or dispersal of seeds or pollen. Gene flow can reduce the potential for local adaptation within each population because it introduces new alleles that may not be well suited for the local environment. For example, if a population of plants has evolved to tolerate drought, but some individuals migrate from a wetter area and bring alleles that increase water uptake, this could lower the overall fitness of the population in dry conditions. Gene flow can also reduce genetic variation within populations by making them more similar to each other, which can limit their ability to respond to environmental changes.
