Trauma And Its Effects On Dominant Or Recessive Genes
Though trauma may be hereditary, it should not be made an excuse of one’s actions. I believe that it only takes one to break the chain of abuse. However, with recent studies, it has come to light that traumatic events can alter a person’s DNA allowing the effects of trauma to be carried throughout generations. As a result, this could make the breaking the chain incredibly more difficult in that the future generation is affected by the same trauma. Trauma is passed down through genetic markers that in the form of tags that form â€Å"to biologically prepare offspring for an environment similar to that of the parent.†(Yehuda). These tags that can the opposite effect on dominant or recessive genes. For example, if the gene is dominant, it may become recessive. As a result, the gene’s functionality has been altered thus causing a permanent change in the descendant’s DNA. According to Moshe Szyf, a researcher at McGill University, â€Å"the genes were switched off in response to a series of events, such as abuse during childhood†. For example, if even one person is traumatized by experiences, the generations after can acquire the same epigenetic modifications on their DNA. But this does not mean that only the ancestors trauma can affect the descendants, new trauma can also occur at any time in the line and not just a reaction to the original trauma. Therefore, the new markers that form would be passed down as well. So instead of just one person affected, many are because if the originalShow MoreRelatedOsteogenesis Imperfecta ( Oi ) Is An Inherited Disorder Characterized By Extreme Fragility Of The Bones1563 Words  | 7 PagesIn some cases, an ultrasound can identify bone abnormalities at 14-18 weeks. Cells obtained through chorionic villus sampling or amniocentesis can also be analysed for a genetic mutation. Amount of collagen can be tested through a skin sample and genes can be tested through a blood sample and X-ray s to check for bone abnormalities such as the symptoms explained earlier can be used to diagnose.

The inability to breakdown or absorb certain things in food can also cause chemical build-up in the blood leading to the damage of other organs. This could be a symptom of a recessive disease that both parents are carriers of, resulting in the child having an affected chromosome or gene. This could be why Emma and Jacob’s other son died in the first few days of its life, and went undiagnosedRead MorePreventing Genetic Disorders With Gene-therapy Essay2241 Words  | 9 Pagesmean though? How will this help mankind? One area to which this knowledge can be applied is in the area of gene-therapy. Gene-therapy is now being tested to treat and cure some common genetic disorders. Like all new research, gene-therapy is the center of much controversy. A discussion of genetic disorders and current prevention methods is enlightening. In addition one must understand what gene-therapy is and how it is being used. In order to understand how genetic diseases are formed, it is importantRead MoreChild Development: Heredity and Environment1240 Words  | 5 Pagesdirect environment or the nature surrounding an adolescent directly influence acts of delinquency, later progressing further into more radical crimes such as murder or psychotic manifestation, or is it directly linked to the hereditary traits and genes passed down from that individual adolescent’s biological parents? To answer this question one must first understand the difference between nature, nurture, environment, and heredity. Nurture, broken down further into environment, is defined as variousRead MoreEffects On Heritability And Environment : Twin And Family Studies1832 Words  | 8 Pages Whitney Davis Nova South Eastern University The Effects on Heritability and Environment: Twin and Family Studies Abstract Many internal and external components collide in order to create individual personalities, behaviors unique to every individual person.

This mutation is an autosomal dominant disorder; this means it affects those who are heterozygous with a homozygous recessive partner because of this it means their children will have a fifty percent chance of having FOP. Most cases of FOP are a result from new mutations in the gene. People who have FOP and have the heterozygous phenotype have less severe affects than those who have the homozygous dominant phenotype.

Neonatal jaundice causes bilirubin encephalopathy (kirnicterus) which is not common today with Rh immunization and other clinical advances that prevent the massive lysis of child RBC’s (3). Genetic causes of CP have been linked to an autosomal recessive gene in a few cases of the ataxic diplegia form (4). Infancy attributions include head trauma and meningitis (3). The original thought was that CP was a result of birth trauma and the physician’s competenceRead MoreThe Work Of The Working Brain1898 Words  | 8 PagesDiseases are classified as sporadic and degeneration affects the upper and the lower neurons may be even both.

Neuropathic pain results from primary injury to the peripheral or central nervous system and is not the result of pain signaling from peripheral tissues or organs. Peripheral neuropathic pain is caused by peripheral nerve trauma, diabetic or alcohol abuse-induced neuropathy, carcinoma, nutritional deficiencies, and human immunodeficiency virus (HIV). Central neuropathic pain is caused by a lesion or dysfunction in the CNS (brain or spinal cord).
