Answer:
Hereditary transmission of the defected genes to the offspring.
Explanation:
The answer is either A, the bottleneck effect or C, natural selection. The answer is most likely A because it is hinted that the predator fish was placed in the isolated stream. The predators eating the darters less than 5cm is natural selection though.
The property rights approach to environmental issues often becomes highly relevant in cases involving endangered species.
The approach based on property rights postulates that if exclusive property rights are correctly established, the public good of maintaining high environmental quality may be converted into a private good, and the best possible distribution of environmental resources will be accomplished.
The protection of people's property rights is an efficient method for preserving and rehabilitating endangered animals. It is more likely that recovery will occur if these animals are owned by someone who will benefit in some way from their growth. But if endangered species are nothing more than a burden, any kind of financial incentive to preserve them is met with fierce opposition.
