Part C Maize Genetics Seedling CharacteristicsIn corn, tall (7) is dominant over dwarf (t). Predict what phenotypic ratio of tall to dwarfplants you expect to observe.18. What is your expected monohybrid F2 phenotypic ratioYour null hypothesis is that there is no difference between your observed ratio and the expectedratio. Your alternative hypothesis is that there is a difference between your observed ratio andthe expected ratio.Observe the flats of seedlings grown from F2 seeds resulting from crossing F₁ hybrids.Monohybrid Cross:19. Record data below.Number of tall seedlingsNumber of dwarf seedlings.20. What are the phenotypes of the F2 generationOf the F₁ generationOf the parents66 ly emergenBIO 103 1Mo21. What are the genotypes of the F2 generationOf the F1 generationOf the parents22. If it were possible, how would you determine whether a tall individual is heterozygous orhomozygous?_23. How do the observed phenotypes of your seedlings compare with the expected F₂ ratio?To calculate your expected ratio numbers given the total number of seedlings that you counteduse the following steps:A. Determine your expected ratio. For a monohybrid cross between two F₁ plants, bothheterozygous for the trait, you would expect a 3:1 ratio. If you add 3+1, it equals 4.Therefore, each category is a fraction of 4. This means that you expect the followingfractions 3/4 and 1/4 for the two phenotypic class.B. Determine your total number of corn plants actually counted.C.Multiple each fraction by the total number of seedlings you actually counted.a. For example, if you counted 85 seedlings, you would expect the following:3/4 X 85= 64 tall seedlingsi.ii. 1/4 X 85= 21 dwarf seedlingsD. Add the 2 resulting numbers to verify that they add up to your total numberE. Compare the 2 resulting numbers (your expected numbers) to your actual numbers usingChi Square statistical analysis (to be completed later in Exercise III).Exercise II: Dihybrid CrossDihybrid crosses involve the inheritance of two different traits. Using the same stepshove in the monohybrid crosses, fill in the outline below for the following dihybrid crossant) TT, broad-leaf (recessive) bb plant is crossed with a short (recessive) tt,ant) BB plant.Parent 2+BB
