Natural calamities like earthquakes and volcanic eruptions, which kill the majority of people, are shown during which effect?
Bottleneck Effect
Founder effect
Gene flow
Genetic Drift
Answers (1)
-
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. This is shown during natural calamities like earthquakes and volcanic eruptions, which kill the majority of people.
-
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.
-
The transfer of genes between populations, species, or creatures is known as gene flow.
-
Smaller populations are typically where genetic drift happens. Any allele can go extinct in a small population with a lot of alleles.
-
Hence, option 1 is the correct answer.
