Final answer:
Human-induced selection regimes in natural populations involve human activities that influence trait frequencies, such as artificial selection and environmental factors like pollution. These activities can lead to microevolution and a deviation from the Hardy-Weinberg equilibrium. The correct option is C.
Step-by-step explanation:
Human-induced selection regimes in natural populations involve C) Human activities influencing trait frequencies. Examples of how human activities can influence genetic variation include artificial selection and environmental factors like pollution. Artificial selection is where humans selectively breed plants and animals with desirable traits.
On the other hand, natural selection is the process where traits beneficial for survival and reproduction are favored without human intervention. Human-induced changes can lead to deviations from the Hardy-Weinberg equilibrium and result in microevolution of populations.
It is important to differentiate between human-caused events, like environmental pollution impacting genetic diversity, and natural events, such as genetic drift resulting from disasters leading to the bottleneck effect where large portions of a population and their genetic traits are suddenly diminished.
