Behavioural genetics

sections in which the repeats vary in number per individual, here the VNTR’s chosen were D1S80 and D3S1358. The second centred on Restriction Fragment Length Polymorphism (RFLP) analysis and how the technique lends itself to the identification of genetic diseases. Each experiment…

Not only can genetic databases be of use in the medical field, but also for FBI purposes. With the help of a national genetic database, the FBI would be able to quickly identify missing persons, cadavers, and criminals. The intention of obtaining a genetic database is to solve murders and identify other victims that could only previously be identified as Jane or John Doe. The International Homicide Investigators Association claims that nationally there are more than 40,000 unidentified cadavers.…

Speciation is how new species are made which involves a form of isolation (Lewis et al., 2013, p. 103). It also is about the divergence of genetic information between two species that once were the same but they separated and were unable to reproduce with one another and over time as they evolved they become genetically different due to these conditions (Lewis et al., 2013, p. 103). An important…

smallest of sea creatures. Since then, there have been many waves of evolution, and with genetic engineering, humankind will be able to remain adjustable to lifestyle and environmental changes. It may potentially be the peak of the “fittest” that Darwin proposed in 1869. Genetic engineering is not a science fiction fantasy anymore either- is it legitimate and it is growing. Will you grow and adapt with genetic engineering, or will you be destined to natural selection as the world around you…

A genotype is known as the complete genetic makeup of a given organism. Consequently, a genotype is the one responsible for the phenotype of an individual. In eukaryotes, a single genotype is capable of expressing more than one phenotype (observable characteristics). This possibility is because genes can go through lots of differentiation processes like mutation, changes in gene expression and frequency. So, mutations play a significant role in variation. For example, DNA can be affected by the…

status by technology. Though we are aware of the progress in certain fields of technology such as communication, transportation, and healthcare, there are new advancements that could alter the course of human evolution as we know it. The study of genetics first began in the mid 1800’s and in only a hundred and fifty years it has opened up possibilities beyond anything its discoverers could have imagined. The term ‘designer babies’ was originally coined by journalists with a simple and somewhat…

The heretical concept of antimicrobial resistance: In mid 1950 which is known to be one of the most significant year of Medical science when genetically transferred antibiotic resistance was identified in Japan and a theory has established on the basis of scientific data is that during Bacterial conjugation resistance genes or r genes are propagated from one strain to an entire population. Therefore Bacterial Genome evolution has started taking place as one of the major fields in Microbiology,…

Originally it was believed that all traits are blended together. Due to the work of Gregor Mendel, though, it was shown that characteristics are a result of inherited factors, known as genes1. Genes are units of heredity on a chromosome that bring about our existence and create diversity. This diversity arises from the fact that there are different forms of genes known as alleles. All the alleles of an organism are referred to as that organism’s genotype and results in an organism’s phenotype,…

Due to limited time constraints and having lab only once a week this lab was broken up into five periods, the last one specifically to go over the results. Day one consisted of extraction of plasmid DNA, which we used Resuspension Buffer to break up our pellet after removing the supernatant (liquid) after centrifuging our overnight culture. Then Lysis Buffer was used to break down the membrane of the cells so that we could then add Neutralization Buffer to bring our sample from basic to neutral…

•Explain what is involved with this biological issue Genetically modified organisms, also known as a transgenic organism, are living organisms whose genetic material has been artificially altered in a laboratory using genetic engineering(GE) techniques. Every genes hold information that will give the organism a trait which is similar to phenotype. Genetic engineering technique involves the process of taking genes…
