Demonstrate understanding of human manipulations of genetic transfer and its biological implications. Since 12,000BC, humans began to genetically modify organisms. Genetic manipulation is a process of directly modifying an organism’s genome using biotechnology. For this process to occur successfully a clear procedure and a set of technology is needed. This enables genetic makeup of cells and transferring genes across species boundaries to produce improved organisms with desired traits. The first person to accomplish the direct transfer of DNA from one organism to another was Herbert Boyer and Stanley Cohen in 1973. Ever since, there have been multiple genetically manipulated organisms varying from plants that are resistant to viruses to animals with more meat and even for medical purposes. There are four ways which humans use mainly to manipulate genes, these are; selective breeding, assisted reproduction, cloning and genetic modification (genetic engineering). The two gene manipulation methods that I will be looking at are selective breeding and animal cloning. Selective breeding is when animal breeding or plant breeding is controlled by humans to manipulate the genetic makeup. This is when humans choose specific traits that benefit them and control the breeding to create more. For thousands of years humans have been selectively breeding animals and plant for their own desires and in doing so, we are controlling the diversity of DNA in the populations. The
