A skin and respiratory fungus killed most of the tree frogs in a hypothetical forest in the state of Washington. The population dropped from 1,200 to 320. Scientists caught 25 frogs and, in an effort to help preserve the species, started a new population in a similar forest in the eastern portion of the state of Oregon. Which of the following factors would probably have the least impact on this new population?
Savage is a frog biologist at the University of Central Florida in Orlando. She catches amphibians like this tiny cricket frog to sample their skin cells. She wants to know which ones host a killer fungus. Huge numbers of frogs have been dying from a skin disease that it causes. But the fungus doesn’t kill off every infected frog. Savage is trying to figure out why. She thinks it might have something to do with the animals’ genes. hence the correct option is "The founder effect,since there would be a large population with immigration.
