Behavioural genetics

For this lab we conducted a population genetics study on the frequency of wild and apterous flies within a small population of fruit flies. The fruit fly Drosophila works well for genetic and evolutionary geared studies because they have a relatively short generation time but are intricate enough to reveal some biological principles that are parallel to many different kinds of eukaryotic organisms. When exposed to artificial selection in laboratory experiments, fruit flies have experienced…

the children they would have from that point forward would not be born with the mutations that would cause some of the genetic medical conditions. Marcy Darnovsky, executive director of the Center for Genetics and Society, stated that, “Allowing any form of human germline modification leaves the way open for all kinds — especially when fertility clinics start offering ‘genetic upgrades’ to those able to afford them,”…

Deteriorate Muscle And Hope Need an attention-getter. In 1861, Guillaume Benjamin Amand Duchenne wrote De L'électrisation Localisée in which he described the disorder now referred to as DMD. Although later discovered, Edward Meryon described this genetic disease first, but by that time it had the title of “Duchenne” (Abramovitz p. 19-21). Out of nine different types (“Duchenne”), Duchenne MD, the most common of childhood muscular dystrophies (Abramovitz p. 19-21), is known as the second largest…

mutated. Then they were able to compare gene with other medical issue that have the same gene mutation. The usage of genomic analysis is not available for most patients, because each person has different genetic codes. The same drug might not work on other people. Because each person has different genetic code, it is hard for doctors to create drugs for each…

reabsorb sodium from sweat after it is brought to the surface of the skin, giving people with cystic fibrosis abnormally high levels of sodium in their sweat therefore, testing sodium levels in sweat is one way to test for the disease. Third, is a genetic test can be performed to test for the abnormal CFTR gene that is affected by cystic…

Genetic Engineering is the modification of genes that ultimately improves the organism being engineered. Most of the genetic engineering done today is used on crops and animals, but some is also used in humans as well. Creating things like herbicide resistant crops and faster-growing animals have turned out to be very efficient in many ways, but no matter how great they are, they were always questioned and seen as unnatural (Erickson, 2012). Today, genetic screening is done on human fetuses to…

Introduction Genetics is the process of inheritance of traits from parents to offspring, including the molecular structure and function of genes. Epigenetics is a new discipline in which the word “epi” means above that is epigenetics means above genetics or the control above genes. Aaron et al., defined “Epigenetics as a bridge between genotype and phenotype- a phenomenon that changes the final outcome of a locus or chromosome without changing the underlying DNA sequence” [1]. Epigenetic gene…

Dysarthria is a speech disorder caused by a stoke, cerebrum damage, tumors, or Parkinson's disease. Dysarthria damages movements in muscles used for speech production. These muscles incorporate the tongue, vocal folds, lips and diaphragm. Dysarthria is weakened in communication due to shortcoming, loss of motion and incoordination of speech. It influences your pitch, loudness, voice quality, prosody, respiration and articulation. There are numerous sorts of dysarthria's, which are…

elegans is very suitable for genetic study with its short life cycle, two sexes of both self-fertilizing hermaphrodites and males, and easy cultivation in the laboratory, which makes it easy for researcher to perform genetic crossing (BRENNER 1974). Second, although the adult hermaphrodite has only 959 somatic cells, it contains many different organs and tissues including muscle…

In the article “Growing Doubt: a Scientist’s Experience of GMOs” in the Independent Science News Food Health and Agriculture Bioscience News, Jonathan Latham, a plant biologist, expresses in his experience Genetically Modified Organism’s quick transition from the lab to the industry, the high risks of Genetically Modified Organism plants, and the dangerous toxins that are placed inside Genetically Modified Organism plants. Jonathan Latham explains, in the beginning of his research he worked in…
