The world's population of cheetahs has very little genetic diversity. The population has dropped drastically in recent years and the bottleneck effect has altered genetic frequencies. What mechanism o?

The mechanism at play here is called the bottleneck effect. This occurs when a population experiences a drastic reduction in numbers, leading to a loss of genetic diversity and a shift in genetic frequencies. In the case of cheetahs, this has resulted in decreased genetic variability and potential negative impacts on the population's survival and adaptability.


The drastic reduction in genetic variation that results when a new isolated population is established by a very small number of individuals from a larger population is known as?

This is known as a genetic bottleneck. It can lead to reduced genetic diversity, which may make the population more susceptible to diseases and environmental changes, increasing the risk of extinction.


Which would be the most likely effect of a drastic reduction in all the producer organisms in a meadow environment?

A drastic reduction in producer organisms in a meadow environment would likely disrupt the food chain, leading to a decline in herbivore populations due to lack of food. This, in turn, would impact predator populations that rely on herbivores for food. Overall, it could result in a significant shift in the ecosystem's balance and biodiversity.


How do the founder effect and the bottleneck effect differ, particularly in the context of genetic diversity and population size?

The founder effect occurs when a small group of individuals establishes a new population, leading to reduced genetic diversity. The bottleneck effect happens when a population undergoes a drastic reduction in size, also resulting in decreased genetic diversity. The main difference is that the founder effect involves the initial establishment of a population, while the bottleneck effect involves a sudden decrease in population size. Both effects can lead to genetic drift and increased risk of genetic disorders.


A change in relative frequencies of alleles in the gene pool of a population is called?

A genetic drift is a random change in allele frequency over time that is brought about by chances. A bottle neck is a drastic reduction in population size brought about by severe pressure.

Does any one know any good ideas for a world hunger essay?

Severe and drastic population reduction would benefit humanity more than any other. With a population of 500 million the human race will survive much longer than our current population.


What are two types of genetic drift?

Founder effect- isolation of few individuals from larger population; new population forms with different gene pool. Bottleneck effect- Drastic reduction of population size leading to a restrictive gene pool in wich the population must use to recover. Forms population with different gene pool.

Half of the polar bears in a small population die. This population may experience changes due to .?

The drastic reduction in the polar bear population can lead to genetic bottlenecks, resulting in decreased genetic diversity which can affect their adaptability to environmental changes. Additionally, the loss of individuals may disrupt social structures and mating patterns, potentially leading to further population decline. The remaining bears may also face increased competition for resources, impacting their survival and reproductive success. Overall, these changes can threaten the long-term viability of the population.
