Three studies have analyzed the impact of the introduction of GM crops on within-crop genetic diversity. Reciprocal recombination arises via the exchange of genetic information between two nonsiscer chromatids. Genetic Diversity Analysis. Molecular markers such as RAPD, ISSR and AFLP technologies were used in this work to detect genetic diversity of the selected medicinal plants.

The entire population of plants would die because none would carry genetic variants that might confer resistance to the virus.
