In the dihybrid cross you have considered two traits at a time. Although the number oftraits has increased by one, what has happened to the number of possible phenotypes ofoffspring produced in the F2 generation? For21. What are the genotypes of the F2 generation.Of the F₁ generation.Of 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:i. 3/4 X 85= 64 tall seedlingsii. 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 stepslisted above in the monohybrid crosses, fill in the outline below for the following dihybrid cross.A tall (dominant) TT, broad-leaf (recessive) bb plant is crossed with a short (recessive) tt,narrow-leaf (dominant) BB plant.Parent 1GametesF₁ OffspringParent 2Gametes67
