Genetics Essay

There are around 6,000 known genetic disorders (Genetic Disease Foundation). The symptoms of these disorders range from memory loss to blindness, physical abnormalities and more. A process known as gene editing was created in an attempt to do away with genetic disorders. Gene editing was named “Science Magazine 's Breakthrough of the Year 2015” due to its ease and high accessibility (ScienceDirect). It works by using CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) and Cas9 to make

Genes located on the same chromosome are linked. They can become unlinked, or separated, in crossing over with the frequency of separation being higher the further apart the genes are on the chromosome. The relationship between the frequency of genes separation due to crossing over and the distance between genes is inversely proportional. That is the further the genes are away from each-other the more likely they will cross over. The frequency of crossing over, also known as the recombinant frequency

Regina Noel 10/19/2016 Epigenetics: Genetic and Non-Genetic Mechanisms of Inheritance When discussing the topic of genetics, it is typically viewed from the perspective of Mendelian inheritance in which genes are transmitted from parent to offspring solely through the use of genetic alleles, which are the alternative form of genes that have varying DNA sequences and chromosomes that affect the phenotype, visual gene trait (Toth. 2015). If and how a genetic trait is expressed is whether the alleles

A genetic disorder is a disease that is caused by missing or abnormalities in the chromosomes of a human. Finding out if an offspring has a genetic disorder can be determined by using basic genetics. The Punnett Square, a diagram used to predict the results of a crossing or breeding of two species, can determine the outcome of an offspring by using the genotypes of both parents. Pairing the genotypes of both parents together can show the four different genotypes of offspring, two being female, and

Ethical Issues Surrounding Genetic Screening and Genetic Engineering In today’s modern age science is moving at a rapid pace; one of those scientific fields that has taken the largest leaps is that of genetics. When genetics first comes to mind, many of us think of it as a type of science fiction, or a mystical dream. Yet genetics is here, it is real, and has numerous ethical implications. One of the particular areas of interest is prenatal genetics. In this field, many new and

2.5 Number of genetic clusters To infer genetic cluster number (K) in our sample set, we used two Bayesian approaches based on the clustering method which differed in that they: a) incorporate or not a null allele model, and b) use a non-spatial or spatial algorithm. We selected this approach because Bayesian models capture genetic population structure by describing the genetic variation in each population using a separate joint posterior probability distribution over loci. First, we used STRUCTURE

Introduction After voluminous amounts of studies, it is known that million years ago, the first human arose from our beloved ancestor, the Great Ape and just as humans arose, so has the way research can be approached. Molecular data can be used in modern phylogeny as a form to study evolutionary biology. This approach is practical because it uses extracted DNA and protein sequences to do an analysis on the sequence by finding similar sequences to it, in which help in phylogenetic reconstruction

coverage but also with employers. Once the genetic information is part of the individual’s medical record, it may then be accessed by others. Cases of employers having used genetic information as part of the selection process have been found in Australia. Genetic discrimination has even been detected in the armed forces where a young man was asked to provide documentation that showed he was not predisposed to Marfan syndrome, of which he had a family history. Genetic discrimination is probably the biggest

What is genetic counseling? What is a genetic counselor? Those questions and more are some things I remember thinking about in my sophomore year chemistry class. I was so intrigued, yet I had no idea what any of it meant. At the time, I had no idea how common they were, and just how much genetics advanced every day while I was clueless. Our genes are what make us who we are. Humans share 99.5% of our DNA with each other. That means that every piece of DNA that makes us different is only .5% of

The field of genetic engineering is an incredibly growing one and it proves to be a topic of constant controversy. Some believe it to be beneficial to humanity, while others argue that it poses a threat. Several documents have been published, and experiments tested to support both sides of the spectrum, but follow of the trend of supporting genetic engineering. While certain aspects put some moral codes into question, genetic engineering is beneficial to humanity because will lead to a more understanding
