Scientists in many parts of the world are trying to introduce genetically modified seeds in the agriculture sector for better yield as well as for the resistance of drought and flood situations. At least some individuals have a better chance to inherit genetic characteristics that are vital for their survival Dr. Richard Lankau, “Diversity within a species is necessary to maintain diversity among species. Genetic diversity. BAM-15-57 Furthermore, recent studies reveal that the variation between any two individuals is very small, on the order of one single nucleotide polymorphism (SNP), or single letter change in our DNA, per 1,000.

Here, we examine two broad classes of genetic diversity: genotype-based and genome-based measures. If any one type is removed from the system, the cycle can break down, and the community becomes dominated by a single species (National Science Foundation, 2007) 19 examples: We conducted a laboratory experiment to evaluate the role of parasite genetics… GENETIC DIVERSITY Each member of any animal or plant species differ widely from other individual in its genetics makeup, owing to the large number of combinations possible in genes that give every individual specific its characteristics.
