Genetics and the studies which investigate the genome of living organisms are important in the investigation of populations in reference to their distribution. It is thus through genetics that we are able to define the existence of racial differences and the patterns which describe the behavior of each population (Betz-Zall 109). Genetics has enabled scientists to come up with medicine for the therapy of various conditions which affect human beings and animals. For example studies on bacteria and viruses in relation to their genotypic expression illustrate the move towards making medical realities possible (Coates, John and Andy 18). It is thus through studies in genetics that the life of animals and human beings is conserved. Additionally, the study of genetics enables the achievement of preservation of the plant kingdom. This is made possible through the enhancement of genotypic makeup of plants which is geared towards the enhancement of the ability of plants to survive in various environments (Geck 153). The history of genetics is demonstrated by the application of genetics in the improvement of human, animal and plant life through cross breeding techniques. The work of Gregor Mendel defines the future of genetics by illustrating how the genotypes of organisms are passed from the parents to the offspring (Betz-Zall 109). It is thus through future studies of the genotypes of living organisms that the changes in the populations of the world is to be defined and determined (Mark, Hon and Roger 58). The blending of genes to come up with a unique living organism is a historic feature of genetics which has been used to cause changes in the offspring. These changes are aimed at ensuring that the genotypic and phenotypic structures of living organisms are designed to enhance their survival within the competitive environment (Coates, John and Andy 19). Nonetheless, the studies which enhance the feature of living organisms are procedural in addition to contextually long lasting through the results are beneficial to the enhancement of life of human beings, plants and animals (Mark, Hon and Roger 67). Reproduction is a concept of genetics which illustrates the role of genes in the perpetuation of the offspring. It is through the combination of the male and female genes that the existence of a population is made possible (Betz-Zall 109). The study of these genes therefore plays a leading role in ensuring that the life and existence of life is not extinct. Additionally, the human and animal genome and the related studies ensure that the existence of life is achieved through improvement of the previous genotypic and phenotypic expressions. More importantly, the conviction of nurture within the nature of life as expressed through genes is achieved through genetics and the related studies (Geck 153). Nurture explains that in addition to the role of genes in the living of organisms, the environment also plays a role. It is in this sense that it is understood that the level into which genes contribute to the expression of living organisms is also influenced by external factors within the environment (Mark, Hon and Roger 65). The significance genes are further demonstrated by the diversity which is expressed within the human, plant and animal kingdoms (Coates, John and
