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

Text Solution

Verified by Experts

(i)Fewer individuals in a species impose extensive inbreeding among them.This limits the appearance of variation and puts the species at a disadvantage if there are changes in the environment.
(ii)Since ,the individuals fail to cope up with the environmental changes ,they may become extinct.
(iii)In a large population appearance of variation is more rapid.These variations intoduce many useful modifications and help them in adapting to the ever changing environment.

Assertion :Species with low genetic variability are generally at greater risk of extinction than the species with more genetic variability. Reason: Species with low genetic variability are more vulnerable to disease, predators or other environmental challenges.

Assertion : Over-exploitation of a species reduces the size of its population eventually leading to its extinction.

(c) If assertion is true but reason is false. (d) If both assertion and reason are false.

Assertion : The Nile perch introduced into lake Victoria in east Africa led to the extinction of an ecologically unique assemblage of more than 200 species of cichlid fish in the lake. Reason : When alien species are introduced deliberately for economic or other uses, they often become invasive and cause extinction of indigenous species. (a) If both assertion and reason are true and reason is the correct explanation of assertion. (b) If both assertion and reason are true but reason is not the correct explanation of assertion. (c) If assertion is true but reason is false. (d) If both assertion and reason are false.

Assertion : Critically endangered category includes the species which have sufficient populationa at present but is undergoing depletion due to some factors. Reason : Vulnerable category includes the species which are facing very high risk of extinction in the wild an can become extinct any moment. (a) If both assertion and reason are true and reason is the correct explanation of assertion. (b) If both assertion and reason are true but reason is not the correct explanation of assertion.

Which of the following statements describe natural extinction ? (i) Extinctions abetted by human activities (ii) Slow replacement of existing species (iii) Also known as background extinction (iv) A small population is most likely to be extinct (a) (i) and (ii) (b) (i), (ii) and (iii) (c) (ii), (iii) and (iv) (d) (i), (ii), (iii) and (iv)

Where would the greatest number of endemic species occur and why ? (a) Small volcanic archipelagos, such as the Galapagos Islands, because the abundance of unoccupied habitats favours the adaptive divergence of colonists from nearby mainland populations. (b) Large oceanic island, such as Australia, because the inhabitants have been isolated from mainland populations for a very long time. (c) On rugged landscapes, such as Patagonia, because of the high levels of natural disturbance by glaciers and earthquakes. (d) Temperate woodlands, such as those in southern England, because of the high levels of disturbance by human activity and the history of artificial selection.
