Population genetics

include natural selection, mutation, gene flow, and genetic drift. Natural selection is the foremost force in evolution. It states that biological traits which increase survival will become more frequent in each subsequent generation. It is the most prominent force in evolution because members of a population that inherit these traits live longer, and produce more offspring. Another force of evolution is mutation, the only cause of new genetic material. A mutation is the creation of a new trait…

for your child to live a life free of genetic diseases? Advanced reproductive technologies are now “allowing both doctors and parents to screen embryos for genetic diseases and select healthy embryos”. (“Design-a-baby”)(1) InVitro Fertilization is a process in which you fertilize eggs with sperm in test tubes – this is done within a laboratory, outside of the mother. Techniques such as these assist in preventing the chance of a child being born with a genetic disease. Furthermore, there are two…

The Human Genetic Modification, a new futuristic medical tool, comes as a blessing but also comes as a curse too. Can we even handle this gift that was bestowed to us for its usage? That, however, would be answered; as Opposition. In the articles, “Understanding Genetic (diseases)”, Dr. Maggie Pearce, a Geneticist, stated, “[Broken Genes] Too hard to fix someone’s broken genes”. Likewise, to believers, human genetic modification comes as a blessing to few dozen people, but the thoughts itself…

first of the four forces of evolution is genetic drift. Genetic drift is a random occurrence among species and is a way in which specific individuals' genetics will carry over into the next generation gene pool. This process happens when a species' alleles randomly change frequencies. This happens to the point where a gene is either no longer represented in the gene pool or is the entire representation of the gene pool (more likely with a smaller population). The second of the four forces of…

alleles changes over time in a population. There are four major forces of evolution. These forces may increase or decrease gene diversity, meaning they can introduce new alleles or extinct some alleles. One of the forces is mutation. Mutation is when an error, replication or deletions that cause new genes to arise that neither parents has. This causes the population to become more diversity and is unpredictable. Another force of evolution is genetic drift. Genetic drift is caused when alleles…

Genetics has typically been view as a benefit to society in the aspect of eugenics. Eugenics is defined by Francis Galton as “the study of agencies under social control that improves or impairs the qualities of future generations either physically or mentally”. The statement “improves or impairs” directly correlates to positive and negative eugenics. In the past positive eugenics has been seen through Better Baby and Fitter Familie for Future Fireside contests. These contests were used to…

interaction between a host and bacteria impact the evolutionary processes of both, in a study done on fruit flies. Evolution is the genetic change—the change in the frequency of the genes present—in a population overtime. Coevolution is when two or more species reciprocally affect each other’s evolution. In this study, experimental evolution was done on chosen populations of fruit flies and its symbiotic bacterium, the Wolbachia, when exposed to a virus. Wolbachia are bacteria that inhabit…

Researchers and scientists have now opened a new page in genetics called genetic engineering. With this new technology it has become possible to bypass the laws of nature that seem impossible to bypass. Evolution for instance, natures train tracks, you can’t get off of them without a catastrophe happening, or can you? Actually, scientist and researchers alike believe they can. How you ask? Genetically modified organisms, or GMOs. The odd thing about these GMOs is they are usually thought of as…

Deoxyribonucleic acid is known as the molecule of inheritance where its structure dictates its function in storing the genetic information of the organism (Rafael, 2010). This molecule contains genes which encode proteins needed for the complex biochemical metabolic reactions which occur within the organism (Rafael, 2010). The DNA molecule consists of 2 complementary strands in a helical structure where each strand serves as an informational template for the offspring during duplication (Rafael,…

breed with each other they produce fertile offspring. 2.population is defined as a group of organisms of the same species occupying a particular area that live together. The ultimate 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…
