Scientists observe the frequency of the different forms of the gene and how it changes in response to the environment. Scientists study similar genes that also impact the same traits to see how they work together and influence one another. Scientists study similar genes that also impact the same traits to see how they work together and influence one another. Scientists identify different forms of the gene in individuals from the same species and observe how it shows up as a trait. Scientists identify different forms of the gene in individuals from the same species and observe how it shows up as a trait. Scientists mutate and modify the gene in the lab to see how changes might occur to the organism.

Question

Answer 1

Scientists observe the frequency of the different forms of the gene and how it changes in response to the environment. By studying the distribution of genes like HMGA2 in Darwin's finches, scientists can see how certain traits are selected for or against based on the environment. This demonstrates natural selection in action, as the frequency of certain genes changes over time in response to environmental pressures, leading to adaptations in the population.
