What are the beetles involved in the experiment an example of?

Use your knowledge of science to answer questions below. A certain type of fast-breeding beetle has either large or small mandibles (jaws). The size of the mandibles is genetic. A student takes a randomly selected sample of beetles from the wild and feeds them exclusively on large, hard-shelled seeds. She records the number of large-mandibled and small-mandibled beetles each month, and gets the following data: Month: Number of large-mandibled beetles: Number of small-mandibled beetles: 1 40 60 2 42 55 3 43 52 4 48 50 5 55 48 6 56 51 7 ...
