Answer
The construction of wildlife corridors facilitate the maintenance of genetic diversity in a small, fragmented, and isolated population by the introduction of new alleles.
Work Step by Step
The wildlife corridors plays an important role in the movement of animals and facilitate the continuity of viable populations. If the species are lost from a particular habitat, then the wildlife corridors facilitate the introduction of new alleles into that habitat.
This will helps in counteracting the effects of inbreeding and genetic drift in the isolated and small populations. The genetic diversity is reduced by inbreeding and genetic drift.
