To tackle this question, I’ll first restate what the prompt is asking: which species exhibit greater genetic diversity than humans based on the figure.
Option A: Rats (Rattus norvegicus) and pigs (Sus scrofa).
- If the figure shows genetic diversity levels across species, we would compare the data points for rats and pigs to humans. The reasoning would require confirming that both species have higher diversity than humans. Since the provided answer choice does not align with what the figure indicates, this option appears unlikely given typical diversity patterns where pigs often do not exceed humans in diversity in many datasets, and rats may or may not, depending on the sample.
Option B: Rats (Rattus norvegicus) and Syrian hamsters (Mesocricetus auratus).
- This pair suggests both species show greater genetic diversity than humans in the figure. If the plotted values for these two species lie above the human diversity level (or exceed the human data curve), then this option would correctly reflect the chart’s trend. The conclusion would be supported by the general expectation that some rodent species with large population sizes and broad geographic ranges can harbor substantial genetic diversity.
Option C: House cats (Felis catus) and mice (Mus musculus).
- Here we would need both species to exceed human diversity. It is plausible that mice have high diversity due to large population size, but house cats often show moderate diversity; if the figure shows cats not surpassing humans, this option would be incorrect. If the data show only one of these species exceeding humans, then this option would also be invalid as stated.
Option D: None of the above.
- This would be true only if neither of the listed species had greater genetic diversity than humans. If the figure actually shows that rats and Syrian hamsters do exceed human diversity, then D would be incorrect.
In summary, the accuracy of each option hinges on the specific data points for each species relative to humans in the figure. Given the provided answer choice is B, the figure must depict that both rats and Syrian hamsters have higher genetic diversity than humans, whereas the other pairs do not consistently surpass human diversity according to the chart. This interpretation aligns with the typical expectation that certain rodent species with large populations can harbor substantial genetic variability, whereas other species may not exceed humans in the displayed dataset.
