A very small population of a species faces a greater threat of extinct

1.	A very small population of a species faces a greater threat of extinction than a larger population. Provide a suitable genetic explanation.
Answer» A very small population of a species faces a greater threat of extinction than a larger population because of the following reasons Inbreeding Small population promotes inbreeding. Inbreed results in lesser variations. Genetic drift Small population is vulnerable to sudden change in environment. Because of genetic drift chances of species with small population may wipe out. Inbreeding depression This lead to negative population growth which is detrimental for the survival of the species with smaller population

A very small population of a species faces a greater threat of extinction than a larger population. Provide a suitable genetic explanation.

Answer»

A very small population of a species faces a greater threat of extinction than a larger population because of the following reasons

Inbreeding

Small population promotes inbreeding. Inbreed results in lesser variations.

Genetic drift

Small population is vulnerable to sudden change in environment. Because of genetic drift chances of species with small population may wipe out.

Inbreeding depression

This lead to negative population growth which is detrimental for the survival of the species with smaller population
