Phenotype

always been related to the set of views, predictions and dispositions that concerns culture tied to blood, color and behavior (Wade 5). One genetic marker of Race is phenotypes or often refers to physical appearances. It is the measurable result of genes and environment that is likely to vary by location. Some elements of phenotype like skin color tend to change with geography. Human variation was considered race that explains differences. The study of Goodman et al (97) concludes that the idea…

Nature verses Nurture Nature and nurture is sometimes looked at as a dichotomy. In this paper I will provide multiple reasons why I do not feel this is accurate. The nature and nurture controversy pertains to whether biology, genes, evolution, etc. (nature) explain ones behavior and development or does ones environment, experience, caregivers, etc. (nurture) explain ones behavior and development. However, both are valid when trying to discern the major influences ones development. In professor…

Huntington’s disease (HD) is a late-onset, usually between 35 and 50 years old, neurodegenerative disorder prevalent in 3-7 per 100,000 people of European ancestry1. The disease, inherited in an autosomal dominant pattern2, is characterized by motor disturbance, intellectual decline, and psychiatric manifestations3. The disease is difficult to detect at an early stage of an individual’s life since its symptoms appear in the third to fifth decade of life. To better understand the disease,…

The changes in species have been explored by many scientists, but Charles Darwin was the first to support his findings on the existence of evolution with abundant evidence. Darwin later came to develop the theory of evolution after his voyage on the HMS Beagle to South America in 1831 for five years. Darwin was an English geologist and naturalist who proposed that organisms have had physical and behavioral changes over time to increase reproductive success and to better adapt to the environment.…

vary in terms of risk from common relatively low penetrance genes to rare high penetrance genes1. This project relates to families with rare high penetrance susceptibility genes. Low penetrance susceptibility genes are associated with three main “phenotypes”: pigmentation characteristics associated with a tendency to burn in the sun, increased numbers of melanocytic naevi (moles) or a genotype associated with predicted long telomeres. The most extensively studied gene related to familial…

The racial segregation of Latinos in the public school system is discussed in the film, Lemon Grove Incident, where it examines the 1930’s trial of Roberto Alvarez vs. the Board of Trustees of the Lemon Grove School District that ended school segregation of Mexican children in the district of Lemon Grove, California. The trial is known for it’s success to stop the segregation of Mexican children in the public school system. Although, the case allowed for Mexican integration, it only applied to…

mean? Now it makes sense to me. I also learned how susceptible we are to inherit epigenetic changes due to DNA methylation from our parents. In both videos, they study how two monozygotic twins with the same DNA sequence will exhibit different phenotype and are susceptible to different diseases when they are exposed to different environmental conditions and eating habits. Understanding of…

Introduction Hematopoietic neoplasms can be classified by the French American British (FAB) or World Health Organization (WHO) systems. Both of these systems have their own benefits and drawbacks therefore, this assignment shall focus more on the advantages and disadvantages of both the classification systems. French American British Classification Advantages: 1. This system of classification is easier to use because the cytological details are well discussed and it does not require advanced…

Diagnosis of Neurofibromatosis type 1 is based mainly on clinical findings which meet the diagnostic criteria for Neurofibromatosis 1 which was developed by the National Institutes of Health. Since Neurofibromatosis 1 is caused by heterozygous pathogenic modifications in NF1, molecular testing is rarely needed for diagnosis, and is only useful for certain individuals. The diagnostic criteria for Neurofibromatosis 1 is: 1 they must have six or more café-au-lait macules which are, for prepubescent…

chronic inflammatory skin condition with complex pathophysiology and significant genetic background. This disease is characterized by erythematous, scaling lesions that exhibit variable patterns and body distribution, as well as different clinical phenotypes. Psoriasis can singifincatly influence the quality of life and usually requires lifetime control. Although hippocrates described scaling diseases of the skin under heading 'lopoi', the first clinical description of psoriasis is attributed…
