Recombination in Prokaryotes
We have seen that genetic changes due to mutations can result in the acquisition of new biological characteristics and thereby allow evolutionary change. However, evolution of the fittest organism in a particular environment can be enhanced if transfer of genes between organisms is made possible by genetic recombination. As compared with eukaryotes, where sexual recombination is of ordered nature, in prokaryotes the process is less well developed. It does not involve a true fusion of male and female gametes to produce a diploid zygote.
