Making the world better, one answer at a time. I believe it is necessary to isolate individual colonies from a mixed broth growth because it is the first step in achieving a pure culture for further studies and testing.
The separate populations over time may evolve distinctly different characteristics. If the geographical barriers are later removed, members of the two populations may be unable to successfully mate with each other, at which point, the genetically isolated groups have emerged as different species.Allopatric isolation is a key factor in speciation and a common process by which new species arise.ortions of a populations that exist along the edges of the parent population's geographic territory have higher likelihood of developing reproductive isolation. Such peripheral populations are likely to possess genes that are different from the parental population.
