    In this way, socioeconomics would also be affected if genetic modification was available for the public’s use. Procedures will be expensive; in vitro fertilization already costs nearly $20,000 in the USA without any genetic testing (Regalado 31). The application of improved intelligence, spatial reasoning, and other genetic enhancements will exponentiate these expenses, making genetically elite children available only for those who can pay. This will further widen the inequality gap,…

    Mitosis and meiosis are forms of cell division that produce daughter cells containing genetic information from the parent cell. Mitosis is the division of the genetic material in the nucleus which is immediately followed by cytokinesis. On the other hand, meiosis occurs in sexually reproducing organisms and this type of cell division reduces the sets of chromosomes from two to one in gametes. Both mitosis and meiosis differ, however, both processes result in daughter cells forming. In the end of…

    GENETIC TRANSFER MANIPULATION Humans have been manipulating the natural genetic transfer of animals and plants for a long time. Cloning and selective breeding are well known examples of genetic transfer manipulation. This report will focus on these two manipulations, and the implications they can have on the individuals, and the populations too. In order to show why genetic transfer manipulations are used, and to see the implications of it, the cases of “Dolly” the cloned sheep, and domesticated…

    constituents of population are individual organisms that can potentially interbreed. 3. Genetic variation is very important in evolution process. Mutation, random mating, and recombination cause it. Variation allows changing in genetic pool in a population. Genetic variation enables an organism to better adapt to their climate or environment and so increase the chance to survive in new environment. 4. Genetic…

    Gene editing is the alteration of genes in germ cells which become either sperm or eggs and are inheritable to future generations. Genetic editing has been used in agriculture to enhance crops, it is now being explored in humans too. This technology could potentially eradicate genetic diseases and prevent future generations from passing it on. Gene editing is done through the CRISPR-Cas9 system, where the embryo is edited to the desired outcome. It identifies and attacks the viral DNA and then…

    Leroy et al. (2000) used 4 microsatellite primers to characterise Brassica oleracea accessions. Among the 136 reproducible fragments generated, 25 (18.4%) fragments were common for all Brassica, 27 (19.9%) were unique and 84 (61.7%) were phylogenetically informative. Flannery et al. (2006) assessed polymorphisms in Brassica, Arabidopsis, Camelina, Raphanus and Sinapis using 10 plastid SSR primer sets. Eight loci were polymorphic, and separated the individuals of Brassicaceae into taxon-specific…

    Designer Babies If a parent could insure that their child was born healthy, why should they not? Over the past few years science has progressed in the fields of medical science, and genetic understanding. It is do to these advances that the human race is presented with the choice; alter the path of future generations, or let natural selection continue to reign supreme. Clearly parents-to-be need to take advantage of the medical know-how and worked to strengthen the human race. Even though…

    is genetically identical to its counterpart. DNA cloning is a recombinant DNA technique where cDNAs and fragments of genomic DNA are inserted into a cloning vector and maintained during growth of the host cells. Vector is an agent that transfers genetic material into a cell or organism. Restriction enzymes are bacterial enzymes that find restriction sites and cleaves DNA. restriction enzymes and DNA ligase are utilized to produce recombinant DNA molecules. DNA ligase catalyzes formation of 3′…

    In the beginning of the 20th century, the human mind was much more inclined to search for scientific answers to society’s problems by perfecting the human race by applying the laws of genetic heredity. In 1883, Sir Francis Galton, a respected British scientist, first used the term Eugenics, “the study of all agencies under human control which can improve or impair the racial quality of future generations.” He believed that the human race could help direct its future by selectively breeding…

    the world of genetics and evolution. According to Darwin, evolution refers to any living organism that has developed and diversifies over extended periods of time. Genetics is the branch of biology that studies the genes, which are units of heredity that determine what and how proteins are made, therefore are responsible for what characteristic get passed onto the next generation. Evolution involves many mechanisms besides natural selection, such as mutations because they create diversity and…
