Reduction of gene flow refers to the decreased exchange of genetic material between populations, often due to physical barriers, behavioral changes, or environmental factors. This can lead to increased genetic differentiation and potentially the formation of new species over time. Factors such as habitat fragmentation, geographical isolation, or selective pressures can contribute to this phenomenon, impacting biodiversity and evolutionary processes.

Which term describes the movement of alleles into out of a population?
Gene flow
A sudden reduction in blood flow is called?
A sudden reduction in blood flow is called ischemia. This can lead to tissue damage or even cell death if blood flow is not restored promptly.
A significant reduction in blood flow to the brain is termed?
stroke
Is migration gene flow?
Migration and gene flow are related but distinct concepts. Migration refers to the movement of individuals from one population or area to another, often for reasons such as resource availability or breeding. Gene flow, on the other hand, is the transfer of genetic material between populations, which can occur as a result of migration when individuals interbreed and share their genes. Thus, while migration can facilitate gene flow, they are not synonymous.
When is genetic drift a major factor to evolution?
When there is low gene flow (apex 10.1.2)
What is one of the main causes of speciation?
geographic isolation and the reduction of gene flow
What type of gene flow allows reduction of variation?
Gene flow that involves the movement of individuals from a high-variation population into a low-variation population can result in a reduction of genetic variation. This can happen if the incoming individuals do not introduce new alleles or if genetic drift and selection reduce the frequency of existing alleles.
Which term describes the movement of alleles into out of a population?
Gene flow
What is the movement of alleles into and out of a population called?
genetic flow
What is the movement of gene into and out of a gene pool called?
gene flow
When is a genetic drift a major factor of evolution?
When there is low gene flow.
Movement of genes into and out of a gene pool is called what?
gene flow
Under is condition would a mutation have most impact on allele frequency?
There is no gene flow.
What is the movement of genes into and out of a gene pool called?
The movement of genes into and out of a gene pool is called gene flow. Gene flow occurs when individuals migrate between populations and introduce new genetic variation or when individuals leave a population, reducing the amount of genetic diversity.
The sharp reduction of the gene pool and the numbers of a population through a severe epidemic is an example of?
founder effect, where a small population establishes a new gene pool due to a sharp reduction in numbers.
A sudden reduction in blood flow is called?
A sudden reduction in blood flow is called ischemia. This can lead to tissue damage or even cell death if blood flow is not restored promptly.
Genetic differences between populations tend to be reduced by?
Gene flow tends to reduce diffences between populations.
