Hardy-weinberg principle Hardy-weinberg principle a) Read the principles behind the Hardy-Weinberg principle in Bergstrom & Dugatkin (220-22 *You should have already read this for lecture b) You should know the assumptions that underlie the Hardy Weinberg model. c) You should know the specific kinds of data that are used to determine has Hardy- whether a population Weinberg genotype frequencies. d) You should understand the basic principles of a chi-square statistical test 1. Make sure to bring a cakculator this week. 2. Optional reading from the Bergstrom textbook is on pages 203-215 3. Compieteth following pastice questions Practice Questions leucine aminopeptidase (Lap) gene was ochrogaster). Three different alleles were found. Genotype Number of individuals 100 3 y. 17 14Y 0.1 2 bY AB AC 1. What is the frequency of allele A? a. 0,417 b. 0.492 c. 0.833 d. 0.908 e. 0.088 2. What is the frequency of genotype AB? a. 0.085 b. 0.142 c. 0.833 d. 0.283 e 0.417 3. What is the expected number of genotype AB, assuming Hardy Weinberg equilibrium? a. 9.3 b. 9.5 c. 15.9 d. 19.1 e 38.2 39

Explanation / Answer

here frequency of allele A = number of individual having allele A/ total number of individual

                                      = 100/120 = 0.83

frequency of AB allele is = total number of AB heterozygous / total number of individuals

3. here observed number of genotype is 15.9

                                      =17/120 =0.142
