Discuss the application of each of following in biology today and include three examples of each with a brief description - Essay Example Similarly, forensic scientists utilize the hair to profile the DNA in order to identify the culprits involved in crimes. DNA blood typing is important in paternity testing. The technique identifies the biological parent of a child. Fundamentally, the forensic scientists compare the baby’s DNA with that of the potential father. The commonly DNA blood typing is ABO. The process involves the determination of the antigens on the red blood cells encoded by ABO locus on the human chromosome (Brown, 2010). Notably, the typing can solve the cases of paternity. Similarly, the DNA forensic science can determine the gender by analyzing the Y chromosome. The scientists utilize the amelogenin marker located on the sex chromosome. The theoretical principle in the technique centers on the identical combination of alleles between the son and father (Brown, 2010). Population evolution and microbial life examine distribution, as well as, changes in allele frequency in a particular population. Notably, the population is subject to evolutionary processes that entail genetic drift, natural selection, gene flow, and mutation. The field of population evolution and microbial life is important in enhancing the comprehension of genome changes, plant breeding systems, and medical research. Genomic changes involve the evaluation of particular genes that have evolved in successive generation. It is possible to map the genes to identify the genetic material, which has a casual connection to the phenotypes. Notably, the mapping of genes has been instrumental in the discovery of genetic variants that influence the physical attributes of organisms (Pepper et al, 2009). The plant breeding systems utilize the principles of natural selection to select the plants with the beneficial traits. The technique entails systematic production of the crop populations that possess desirable
