1 Genetics Culminating Project Goal: To create an imaginary organism demonstrating your knowledge of genetics Your organism must display: Two single allele traits (Simple dominance/recessive) One incomplete dominance trait One codominant trait Two sex linked traits Project Checklist: 1. Describe AND draw each of the traits on the list, showing genotypes and phenotypes for each. i. SEE THE SAMPLE SHEET! 2. Draw at least TWO example creatures. The two example organisms must include ALL of your defined traits and the organisms must have different genotypes. 3. Pick one of your single allele traits and create a sample pedigree for your creature and their family. i. The pedigree must include at least THREE generations and a minimum of 20 individuals. 4. Show a dihybrid cross using your two single allele traits. Create two example parent genotypes. (Example: AaBb X AaBB) Calculate the Punnett Square and the phenotypic ratio of the F 1 generation. 5. Solve TWO genetic problems utilizing the Hardy Weinberg equation. 6. Create THREE practice problems using any of your traits. Create and SOLVE your practice problems! 7. Respond to the reflection questions. 8. Submit to Ms. Hogg when complete! Reminders: As always, your work should be neat and legible. You will be given ample class time to work on your individual project, however you must also work on your project outside of class (as homework). This project is worth points. The due date for the project is. Note: For each day the project is late, 10% of the total project grade will be deducted. I will present my project to the class on. References for help: Previously reviewed classroom handouts and homework assignments, labs, pages in the Biology textbook.

5 Hardy Weinberg Practice Problems: 1. Hoggenaters are furry, rambunctious creatures that roam science labs looking for bacteria and viruses. They are also known to infect failing Biology students! They can have black nerd glasses (B) or brown nerd glasses (b). In a sample of 750 Hoggenaters, 15 had brown nerd glasses. Using the Hardy Weinberg equation, estimate the allele frequencies given the population is in equilibrium. Show your work! Answers: BB = ; Bb = ; bb = 2. Assume that a population of Hoggenaters is in equilibrium. The frequency of the (b) allele is 0.3. What percentage of the Hoggenater population is heterozygous for black nerd glasses? Show your work! Answer: % of the Hoggenaters are heterozygous for black nerd glasses

6 Practice Problems with Solutions: Project Reflection: 1. Did this genetics project help to solidify your understanding of genetic concepts? Why or why not? +2 points 2. If you were to complete this project again, what would you change? Why? +2 points

7.012 Problem Set 2. c) If an HhAa unicorn mates with an hhaa unicorn, what fraction of the progeny will be short and brown? Name 7.012 Problem Set 2 Section Question 1 In unicorns, coat color (brown or white) is controlled by a single gene with two alleles, A and a. The brown phenotype is dominant over the white phenotype.
