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

Assertion : Tiger is rare species . Reason : Tiger population is very small .

Read the following text and answer the following question on the basis of the same : Excessive exploitation of species , whether a plant or animal reduces the size of its population , so it becomes vulnerable to extinction . Such as Dodo and passenger pigeon have become extinct due to over exploitation by humans . Thus the world is facing accelerated rates of species extinctions , largely due to human interference . Assertion : Pollution reduces species biodiversity . Reason : Spillover of oil in sea cause death of serval marine animals .

Currently , more than 15, 500 species worldwide are facing the threat of extinction. Out of these , what is the percentage of threatened mammalian species
