You must turn the report in at the start of class (that means 1:00 AM sharp!) December 1‚ 2010. If you come to class late‚ I will not accept your lab report. Please consider e-mailing me your report before you come to class to make sure it is not late. Here is what I expect you to cover in your report: 1. Introduction:

scientific principle known as the Hardy-Weinberg Equilibrium. In this principle it is believe that allele frequencies will remain the same among the different generations‚ depending on whether or not the five assumptions are taking place. In this experiment‚ students put the Hardy-Weinberg theory to the test. Out of the five assumptions‚ only two were conducted in the experiment‚ Natural Selection and Mutation. For those that do not know‚ the Hardy-Weinberg Equation is used to determine genotype

Hardy Weinberg Lab I. Purpose: The Hardy Weinberg principle states that the allele and gene frequencies will stay constant from generation to generation as long as no other evolutionary influences come along. The evolutionary influences can be things such as mutation‚ mate choice‚ selection‚ genetic drift‚ gene flow‚ and meiotic drive. Frequency is the proportion of individuals in a certain category relative to the total number of individuals considered. The frequency of an allele or genotype is

Hardy-Weinberg Principle Name: _______________________________ Period: ____ Show all work and box your answer for each of the following questions! 1. In a population at genetic equilibrium‚ the frequency of allele A is 0.5. a. What is the frequency of the homozygous dominant genotype (AA)? b. What is the frequency of the heterozygous genotype (Aa)? 2. If 16% of the individuals in a population at genetic equilibrium are recessive (aa). a

Place your calculations and data in the space provided below. Once you have calculated the frequencies‚ answer the conclusion questions for each one. Please remember that all calculations must be shown for full credit. Scenario #1 In the year 2050‚ humans have successfully colonized the Moon. The lunar modules created for this purpose could only house

Hardy Weinberg Problems Question 1 5 out of 300 starfish are born with green stripes. These green stripes show that the starfish can morph into other marine animal. Starfish are given this characteristic by a recessive allele. * A) What is the frequency of the genotype of individuals in the population born with green stripes? * B) What is the frequency of the dominant allele? * C) What is the frequency of the recessive allele? * D) What is the frequency of the carriers in

Terrible’ (total range 1.714 - 4.875 ) (Table 2). The expected heterozygosity (He)‚ in average‚ was higher than the mean observed heterozygosity (Ho) for ‘Big Sister’ populations‚ and Ho higher than He for ‘Enfant Terrible’ (Table 3). Departure from Hardy–Weinberg Equilibrium were significant at a 5% level (P<0.001) for only 3 populations (BANA‚ CAMP and ITAR). Based on the estimates of the inbreeding coefficient over all loci‚ the significant deviations were due to an excess of heterozygotes (negative

taste the substances. Non-tasters and tasters of phenylthiocarbamide had nearly the same reaction to sodium benzoate‚ disproving the claim that non-tasters will not experience a bitter response to sodium benzoate. It was also determined that the Hardy-Weinberg Principle results are inaccurate due the the test strips in the experiment being of a low PTC concentration‚ and as many tasters of PTC can actually only respond to high levels of concentration‚ the recorded observations would be skewed. Introduction
Premium Genetics Population genetics Allele
Hardy-Weinberg Equilibrium One of the most difficult concepts to understand about the process of evolution is how changes in the genetic composition of a population affect the phenotypic composition of a population‚ and how both ultimately act to allow evolution of the species. Charles Darwin’s theory of evolution emphasizes that populations‚ not individuals‚ evolve. The purpose of my experiment was to test the allele and genotype frequencies. Alleles for a gene are represented by letters of

Population Genetics / Hardy-Weinberg Problems Directions: Work out the following problems on a separate piece of paper. Show ALL work and circle your answers. 1) If the frequency of a recessive allele is 30% in a population of 100 people‚ how many would you predict would be carriers of this allele‚ but would not express the recessive phenotype? q= 0.30 p= 0.70 Carriers = 2pq = 2(.3)(.7) = .42 #= (.42)(100) = 42 individuals 2) From a sample of 278 American Indians‚ the following MN
