Genetic Drift Quick Check

What is genetic drift?

• the changes in allele frequencies (genes) ,in a population, happening due to random events/circumstances.

• It is an example of primary succession

• Genetic drift are different organisms in a population due to inherited traits from their parents

• It is part of symbiotic relationships such as mutualism, commensalism, parasitism

Genetic drift is change in the allele frequency of a population due to...

• random chance
• natural selection
• non-random mating (sexual selection)
• artificial selection

 Genetic Drift is more likely to happen in... 

• aquatic populations
• small populations
• terrestrial populations
• older populations

All of the genetic information found in a population.

• population

• genetic drift

• evolution

• gene pool

Situation in which allele frequencies change as aresult of the migration of small subgroup of a population is known as:

• founder effect

• genetic bottleneck

• random mating

• natural selection

The formation of new species

• Speciation

• Evolution

• Natural selection

• Mutations

Which of the following is an example of the bottleneck effect?

• Cheetah populations reach their lowest levels with reduced diversity and as they rebound are so genetically similar they appear to be inbred.

• Affected individuals with blue skin can trace their ancestry back to one of the first settlers in the region.

• The environment of a fox population changes and over time foxes who are white survive and pass on their genes to their offspring.

• Humans choose two dogs they like the characteristics of and breed them together.
