- In snapdragons red flower colour (CR) is incompletely dominant to white flower colour (CW). The heterozygote has pink flowers. Normal broad leaves (LB) are incompletely dominant to narrow, grass-like leaves, (LN). The heterozygote has intermediate leaf width. If a red-flowered, narrow leaved snapdragon is crossed with a white-flowered broad leaved one, what will be the phenotypes in the F1 and F2 generations, and what will be the proportions of the different classes? (Draw a branch diagram to provide the answer)In snapdragons red flower colour (CR) is incompletely dominant to white flower colour (CW). The heterozygote has pink flowers.

(You must draw a branch diagram to provide the answer for the F2)In sweet peas, the given enzymatic pathway result to pigment formation in the flowers: A dihybrid plant is crossed to a white one which is heterozygous at the “C” locus (provided in the image). What is the genotype of the dihybrid plant? What is the genotype of the white plant? What kinds of flowers, colored or white, are to be expected from the cross above? Include the ratio.
- Given : The given plant is triploid. Symbol For purple = P For yellow seed = Y For round seed = R Answer 1. The Probability of PpYyRr = 8/64 = 1/8 2. The Probability of PPyyRr = 4/64 = 1/16 3. Probability of at least exhibiting wrinkled seeds = 32/64 = 1/2 4. Probability of at least exhibiting purple flowers = 48/64 = 6/8 = 3/4 QUESTION: Answer the remaining question (5, 6, 7)Two different genes control the expression of kernel colour in Mexican black corn: black pigment gene B and dotted pigment gene D. Gene B influences the expression of gene D. The dotted phenotype appears only when gene B is in the homozygous recessive state. A colourless variation occurs when both genes are homozygous recessive. What would be the phenotypic ratio of a test cross with a plant heterozygous for both traits? Your response must include a Punnett square with appropriate nomenclature. Show the ratio as whole numbers in their lowest form and their corresponding phenotypes.A horticulturist runs a test cross with an offspring (F1 generation) purple plant from Question 8.

Deduce the inheritance of these phenotypes; useclearly defined gene symbols. Give the genotypes ofthe parents, F1, and F2.b. Predict the outcome of crosses of the F1 with eachparental line.In some plants a red pigment is synthesized from a colorless precursor. The addition of a hydroxyl group to the precursor molecule causes it to become purple. In a cross between two randomly selected purple plants, the following results were obtained. 94 purple 31 red 43 white Q:What are the genotypes of the two random purple plants? R/r; P/p X R/r; P/p R/r; p/p X R/r; p/p r/r; P/p X r/r; P/p r/r; p/p X r/r; p/p R/R; P/P X r/r; p/pA) Describe the data you collect from the Purple 1 x Purple 2 cross. Predict the genotype of each of the parent plants. Explain your predictions using data from the experiment. B) Consider the offspring, the next generation (F1), from the Purple 1 x Purple 2 cross.
