Question

Some biologists urge the collection of the few remaining individuals of some of the most threatened amphibian species in order to preserve them if they become extinct in the wild. If such captive-breeding programs could produce thousands of individuals from just a few of the remaining survivors, the species will still be threatened because of ________.

Answer 1

Answer:

the bottleneck effect

Explanation:

• The bottleneck effect is the sharp in the population size due to the fact of the environmental changes such as the famines and the floods and the diseases and other events that lead to the variation in the gene pool s and thus a reduction of the species with a smaller remaining genetic diversity. The genetic drift causes the bottlenecks and this can create a random alternation of the alleles and leads to the loss of the species.
