  • Polymerase Chain Concentration: The Hardy Weinberg Theory Of

    Introduction: Hardy Weinberg theory was an effective tool for recognizing the different genotypes from one generation to the next and each allele frequency. This theory notifies us by how Mendelian inheritance was the lead for all genetic variation and it can be used to follow Mendelian’s rules of segregation and the combination of alleles. Polymerase chain reaction was one of the essentials that is used in the Hardy Weinberg theory of genetic equilibrium which was used in determining the presence of ALU element using TBA 25. The importance of using PCR is to make more copies of small pieces of DNA from human genome to look for the presence of ALU element. Every human genome contains approximately 5% of Alu element. In order for Hardy- Weinberg theory of equilibrium to work, certain conditions have to be taken place such as mating cannot be random, no mutation in alleles, has to be big population, populations have to be separated from each other, and no natural selection. For us to be able to determine if Hardy Weinberg experiment has taken place, we used a type of statistical test to determine the difference between what we expected in terms of what alleles and their genotypes and what we observed in the gel which is known as Chi-square test. This test helped us by using the table to know if our hypothesis should be rejected or not depending on what our P-value which is the probability between what we expected and what we observed is due to random chance. In Hardy Weinberg,…

  • Confirmation Of Mendel's Law Of Segregation

    Confirmation of Mendel’s Law of Segregation I. In Biology class the past few weeks we have been learning about Gregor Mendel. Gregor Mendel is often called the father of modern genetics. Mendel developed the theory of inheritance several decades before the observance of chromosomes via microscope. In Biology lab the past two weeks I completed a series of tests using fast plants, Brassica rapa. The objective of this experiment was to study the Mendelian laws of genetics as they applied to…

  • Lab Report: Genetic Analysis In Plants

    Genetic Analysis in Plants Trev Mumm and Peter Masinelli Life 120 – Lab Section 122 April 28th, 2014 ABSTRACT We completed this lab to classify and count phenotypic traits in plant crosses with one or two segregating mutations, and we also learned how to use the Chi-Square test as a tool to access the statistical significance data collected from a genetic cross. Our hypothesis for the experiment that included green and albino corn genetics, was that the ratio of green to albino…

  • Dosophila Fruit Fly Experiment

    Drosophila melanogaster is also known as the fruit fly. It “has played a central role in developmental biology during the twentieth century”. The fruit fly is considered a model organism for many reasons. Drosophila is low maintenance creatures that are easy to care for. Since they are such a small size, scientists are able to control numerous amounts of the Drosophila melanogaster at any given time. Drosophila reproduces many offspring and the offspring are created in a very fast fourteen-day…

  • Phenylthiocarbamide Analysis

    Analysis of phenotype and genotype using Phenylthiocarbamide (PTC) variation taste sensitivity Introduction Taste occurs when chemical signals stimulate taste receptor cells in the oral cavity to detect tastes such as sweet, sour, salty, bitter and umami. PTC taste sensitivity is very common substance used to study taste perception. Many studies have provided insights into tastes perception using sodium benzoate and thiourea. PTC sensitivity has often been used for practical demonstrations in…

  • Allele Frequency Law Research Paper

    Hardy­Weinberg Law Given the mathematical and statistical methods used already, this law also uses probability, however is represented in a graphical manner. Through this graph I will determine if the class data set has significant variation on an allele by genotype graph by comparing their points to the collection of data sets from Census at School that will represent in this paper as the Canadian average. The Hardy­Weinberg Law, developed by G.H Hardy and Wilhelm Weinberg in 1908, states that…

  • Tay-Sachs Disease

    Tay-Sachs is an inherited disease that destroys neurons in the brain and spinal cord. The most common forms of Tay-Sachs appear in infancy, the infant 's affected by the disease generally show no signs, until 3 to 6 months of age. Infants affected by the disease lose motor skills, they also have a tendency to be startled easily especially by loud noises. Infants will begin to have seizures and develop hearing and vision loss, intellectual disability, and paralysis as the conditions…

  • Essay On Random Breeding

    The results of the statistical comparison of genetic variability between the wild and founding population suggests that because the assumption figure is less than 0.5 (see table 2) the null hypothesis could not be dismissed. This meant that there is was no difference between the wild and founding population’s genetic variability. In relation to conservation biology, this finding is rather optimistic. Due to the fact that the two populations genetic variability is close to one-another allows for…

  • Punnett Squares Lab Report

    This lab was very effective for experiencing the breeding of traits in a realistic simulation and correlating these visual presentations into the Punnett Squares. The objective of this lab was to notice and explore the key differences between genotype and phenotype. Where phenotype is the physical characteristics of a trait, and genotypes are all the possible genetic combinations an organism can obtain from its parental generation. Two mice were used in this experiment, and these two mice were…
