NEET BIOLOGY

Detailed explanation-1: -Species can be especially vulnerable to extinction when the population is small. Smaller populations cannot increase their numbers as quickly as larger populations. This is why extinction is much more likely to occur in species that have low population numbers.

Detailed explanation-2: -Loss of genetic diversity increases the risk of extinction of a population through inbreeding depression. In addition, the number of deleterious genetic variations, which might accumulate in a small population through genetic drift, can also make the population vulnerable.

Detailed explanation-3: -The most at-risk species were amphibians, of which 41% are considered at risk, followed by sharks and conifers, at 37% and 34% respectively. It stated that human activity is having a devastating impact on the environment, but that it is not too late to halt this trend and improve.

Detailed explanation-4: -Maintaining high genetic diversity allows species to adapt to future environmental changes and avoid inbreeding. Inbreeding, which happens when there are small, isolated populations, can reduce a species’ ability to survive and reproduce.
