Inheritance Lab Essay Example | Topics and Well Written Essays - 500 words

Inheritance Lab - Essay Example 2. Identify and record your possible genotypes based on your phenotypes. Genotypes are represented using two alleles. Identify the alleles using the letters indicated below (capital letter indicates dominant allele, lowercase indicates recessive allele): 3. Using your possible genotypes, identify and record all of the possible pairings of parental genotypes that could have led to your possible genotypes. Crosses are denoted in this form: FF x Ff and indicates the genotypes of both parents. You should list all of the possible crosses that could lead to your phenotype. Use the chart below to record the observations of your phenotypes and to record your inferences regarding your genotype and all of the possible crossings of parental genotypes that can account for your genotype. Phenotypes are expressed with a single letter related to the trait. Genotypes include both alleles and are, thus, expressed with two letters (one for each allele). Possible parental genotypes and crosses consist of two genotypes crossed. For instance, a freckled person will have a phenotype of F and possible genotypes of FF and Ff. One of the possible parental genotype and crosses is (FF x Ff). Be sure to list all possible parental genotypes in terms of possible crosses. Crosses are denoted in this form: FF x Ff and you should list all of the possible crosses that could lead to your phenotype. It was observed that the presence of a dominant gene in the genotype always led to the expression of the dominant trait, which is seen as the phenotype. In addition, the occurrence of a certain genotype could result from the crossing of several possible parental genotypes. This lab provided knowledge that recessive traits were denoted by small letters while dominant traits were denoted by capital letters. One component of my genotype came from each parent due to

ACUTE ABDOMINAL PAIN IN ADULTS AND CHILDREN Assignment

ACUTE ABDOMINAL PAIN IN ADULTS AND CHILDREN - Assignment Example The symptoms of acute abdominal pain are nausea and vomiting. Other indications include guarding which is the contraction of abdominal muscles and when pressure is applied to the abdomen. There would be rigidity of the abdominal muscles or rebound tenderness, an increase in severe pain and discomfort when pressure is being applied to the localized area of the abdomen. The patient also has increased white blood cell count. In older patients, presentation delays, coexistent of disease and social and physical barriers complicate acute abdominal pain presentation (Nabi, 2011). There are several diagnostic methods in evaluation of acute abdominal pain. Laboratory tests are done on the blood and urine specimen. The ultrasound is used in the evaluation of abdominal spaces with sound waves while the Computer Tomography (CT) scan is an x-ray technique using a computer program to develop detailed images. The ultrasound and CT are reliable in detecting common diagnoses causing acute abdominal pain. However, the ultrasound misses more cases than CT scan that is more sensitive (van Randen, Lameris, van Es, van Heessewijk, van Ramshorst, Ten, Bouma, van Leeuwen, Bossuyt, Stoker, Boermeester, & OPTIMA Study Group, 2011). Multi-detector CT can be used in evaluating patients with acute abdominal pain. It is an extremely CT noninvasive method for acute abdominal pain diagnosis and management. In the plan of care for patients with acute abdominal pain, the nurse has a key role in the assessment, history taking and management. Assessment is done through physical examination and acquiring diagnostic data. A comprehensive assessment of pain including onset, location, characterization, duration, onset, frequency, quality, and intensity should be performed. Factors such as fear, fatigue and lack of information should be reduced to eliminate factors that may increase the
