Random Chance
Brandyn Is Trying To...
Gene frequencies in a gene pool may shift randomly and by chance This is called?
Random changes.This would be called genetic drift.
A flood kills most of a population of ants that lives near a river. After the flood the ant population increases but its allele frequencies are different. What does this situation represent?
bottleneck (apex) [correct]
Which is an example of genetic drift?
Allele frequencies change randomly each generation. APEX
Species drift to form a new species?
I think you mean genetic drift. Genetic drift is not strong enough in itself to cause speciation generally. Genetic drift is merely a sampling error in allele frequency change due to random events.
When is genetic drift likely to occur?
genetic drift may occur when a small group of individuals colonizes a new habitat
Is genetic drift an example of macroevolution?
No, genetic drift is an example of microevolution.
Which best describes genetic drift?
random changes in allele frequency - apex
What is the term for changes in allele frequency that that happen randomly from one generation to the next?
Genetic drift
What describes genetic drift?
random changes in allele frequency (apex) [Correct]
Is genetic drift an adaptive change?
Genetic drift is considered a form of evolution. If a single population is split into two isolated groups then genetic drift will result in increasing differences over time. Eventually they will become two different species, unable to interbreed even if the two groups are brought back together.
People with one sickle cell are not likely to get malaria what is this an example of?
Genetic drift
When is genetic drift a major factor to evolution?
When there is low gene flow (apex 10.1.2)
What small genetic change such as a single mutation may result in?
genetic drift....
People with one sickle cell allele are not likely to get malaria. What is this an example of?
Genetic drift
Which of the following events do biologists consider a random change?
you do not provide any choices, so it is impossible to answer your question as stated.
A random change in a population's allele frequency?
Evolution is the change in allele frequency over time in a population of organisms. By mutation, genetic drift, gene flow and natural selection.
Gene frequencies in a gene pool may shift randomly and by chance This is called?
Random changes.This would be called genetic drift.
