What happens in case of Bottle neck effect? Tick the correct option.
The bottleneck effect occurs when physical or geographic barriers force a new population to settle in a new area.
Due to competition, predators, or diseases, the population size drastically shrinks in the bottleneck effect.
Both (1) and (2)
None of the above
Answers (1)
-
The founder effect occurs when physical or geographic barriers cause a new population to settle in a new area. The newly generated population does not communicate or mate with the existing population. The new population's allelic frequencies will differ from those of the original population as a result.
-
Due to competition, predators, or diseases, the population size drastically shrinks in the bottleneck effect. Because the organisms that carry particular alleles are eliminated, the frequency of those alleles in a population changes. Since they are the only remaining alleles, the others multiply.
-
Hence, option 2 is the correct answer.
