Question

which of the following statements about gene flow is false? group of answer choices it leads to divergence and the formation of new species. it is facilitated by the movement of individuals between populations. it can increase the genetic variation of a population. it can rescue an inbred population by restoring genetic diversity. it can move alleles between populations, including those that are potentially beneficial.

Answer 1

The answer which is false is, gene flow leads to divergence and the formation of new species.

What is speciation?

For speciation to occur two populations must be prevented from interbreeding.

This means that populations must become isolated from on another through the geographical or biological barriers.

If populations remain isolated long enough, speciation will eventually occur because of changes accumulated in population due to natural selection.

What is gene flow?

Geographical isolation hampers gene flow because of spatial separation which in turn leads of reproductive isolation due to the inability of meeting gametes to leads.

It causes genetic drift due to the barrier of gene flow between them and parent species.

Certain alleles get fixed into population due to inbreeding in a smaller population while other gets eliminated, this leads to formation of new alleles and new gene pool, so-called progressive genetic divergence.

Finally there is the formation of new species when genetic variation are accumulated for several generations.

Answer 2

The following statements about gene flow that is false is that it leads to divergence and the formation of new species.

What is gene flow?

Any movement of people from one community to another, including the genetic material they carry, is referred to as gene flow, sometimes known as migration. Numerous other types of occurrences, such as individuals relocating to new cities or nations or pollen being carried to a new location, are included in the concept of gene flow.

Gene flow has the effect of reducing genetic differences between populations, which prevents or delays the development of populations in various geographic locations into distinct species of the disease. Additionally, phenotypic divergence will be prevented if divergent selection pressures exist but are suppressed by gene flow

Hence  out of following statements about gene flow that is false is that it leads to divergence and the formation of new species.
