Option (C) is not true for species because gene flow means the spread of genes through populations as affected by movements of individual and their propagules, e.g. spores, seeds, etc. Gene flow ensures that all populations of a given species share a common gene pool, i.e. it reduces difference between populations. The interruption of gene flow between populations is a pre requisite for the formation of new species.

Not true for a species: Gene flow does not occur between the populations of a species
Explanation:
Gene flow refers to the transfer of genetic material from one population to another. In the case of a species, gene flow can occur between different populations of the species. This is because members of a species are capable of interbreeding and producing fertile offspring. As a result, gene flow can occur between populations of a species, which can lead to the spread of advantageous traits throughout the species.
Importance of gene flow:
Gene flow is an important mechanism for maintaining genetic diversity within a species. It can also prevent the formation of new species, as it can prevent populations from becoming genetically isolated from each other. In addition, gene flow can help populations adapt to changing environmental conditions.
Other characteristics of a species:
Members of a species share certain characteristics that distinguish them from other species. These characteristics include:
- Members of a species can interbreed: This means that they are capable of producing fertile offspring.
- Variations occur among members of a species: Although members of a species share certain characteristics, there can be variations among individuals.
- Each species is reproductively isolated from every other species: This means that members of one species cannot interbreed with members of another species to produce fertile offspring.
Conclusion:
In conclusion, gene flow can occur between populations of a species, and it is an important mechanism for maintaining genetic diversity within a species. Therefore, option C is not true for a species.
