Gene flow
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.

Floral isolation is a type of reproductive isolation mechanism in plants where differences in floral structures, such as size, shape, or color, prevent effective pollination between different plant species. This can lead to a reduction in gene flow and eventual speciation.
geographic isolation and the reduction of gene flow
Gene flow
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.

There is no gene flow.
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.
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.
founder effect, where a small population establishes a new gene pool due to a sharp reduction in numbers.
Gene flow tends to reduce diffences between populations.
