Answer:
B. Genetic specialization
Explanation:
The characteristic of a population that would most affect the survival of a species, threatened by global climate change is genetic specialization.
Genetic specialization is the term that refers to the forced adaptation that a species has to undergo in order to survive in a given environment. in the case of a region with constant global changes, genetically specialized species may find it difficult to find the food necessary for their survival, and even fail to establish effective reproduction. Thus, the birth rate within this species will be much lower than the mortality rate, and may threaten the survival of the species.
