A small population of insects resides in a series of isolated mountain valleys. Over several generations, researchers observe a decrease in the overall genetic diversity of the population. What evolutionary process is most likely responsible for this observed change?

A population of fish inhabits a large, interconnected lake. Despite the availability of various habitats, the fish exhibit consistent differences in body coloration between different regions of the lake. What process is most likely contributing to the maintenance of distinct body coloration in these fish populations?

A small population of flowers on a mountain plateau exhibits a sudden change in the frequency of a specific petal color trait. The plateau is geographically isolated, and there is no observable movement of pollinators between this plateau and neighboring areas. What evolutionary process is likely responsible for this observed change?

A group of scientists is studying the evolutionary origin of mitochondria and chloroplasts within eukaryotic cells. They observe that these organelles have their own DNA, replicate independently of the host cell, and share similarities with certain bacteria. What theory provides an explanation for the origin of mitochondria and chloroplasts in eukaryotic cells?

In a controlled breeding program for rabbits, humans consistently choose individuals with a specific coat color for mating over several generations. Despite this intentional selection, the frequency of the chosen coat color remains constant. Which aspect of the Hardy-Weinberg equilibrium is likely being met in this artificially selected rabbit population?

In a population of birds, researchers observe a high level of genetic diversity in a non-coding region of their DNA. Despite this diversity, there is no noticeable difference in the birds' physical characteristics or ability to survive. What evolutionary concept best explains this pattern?

In a forest, two populations of frogs share the same breeding pond, but they exhibit different mating calls and do not interbreed. When researchers analyze their genetic material, they find that the frogs from both populations have a high degree of genetic similarity. According to the Biological Species Concept, what is the most appropriate classification for these frogs?
