When a predator goes extinct, all of its prey are released from that predation pressure, and they may have big impacts on ecosystems.” ... “If there are too many deer, for example, they can really change the ecosystem because they can destroy forests, and they also carry disease,” Baldwin said.
The best explanation for the creation of six blacks as well as six albinos from the given cross is that (A) Albinism is a recessive trait; black is a dominant trait.
Albinism is a recessive trait. It is expressed only in an individual's genotype contains a pair of the recessive allele 'a', that is responsible for causing albinism.
Black skin color in guinea pig is a dominant trait which does not allows the recessive trait to be expressed.
Thus, guinea pigs having the genotype 'aa' will exhibit albinism while those having the dominant allele for black color will have black skin color.

Answer:
An endangered species recovery plan is a document describing the current status, threats and intended methods for increasing rare and endangered species population sizes.
Explanation:
When recovery plans are carried out well, they do not simply act as stop gaps to prevent extinction, but can restore species to a state of health so they are self-sustaining. There is evidence to suggest that the best plans are adaptive and dynamic, responding to changing conditions. However, adaptive management requires the system to be constantly monitored so that changes are identified.[10] Surprisingly this is frequently not done, even for species that have already been red listed.[11] The species must be monitored throughout the recovery period (and beyond) to ensure that the plan is working as intended. The framework for this monitoring should be planned before the start of the implementation, and the details included in the recovery plan. Information on how and when the data will be collected should be supplied.
