Gene flow cause speciation because it allows populations to become genetically different.
What is speciation?
- Speciation is the process of creating a new plant or animal species.
- When a group within a species separates from other members of the species and develops its own distinct feature known as speciation.
what is gene flow?
- Gene flow refers to the movement of alleles (genes) from one population to another across geographical boundaries.
- Gene flow is the movement of genes into and out of a population.
- Individual creatures may migrate to new populations and reproduce, or gametes may move .
- for example as a consequence of pollen transfer among plants.
How does gene flow affect speciation?
- By recombining the gene pools of the groups and thereby mending the emerging differences in genetic variation that would have led to full speciation.
- The establishment of daughter species, gene flow strongly opposes speciation.
