- Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?If a heterozygous purple flowering plant is crossed with a true breeding white flowering plant, the ratio of phenotypes in F1 generation will be O1 purple : 1white O 3 purple : 1 white all purple, no white O all White, no purpleYou decide to cross two true-breeding stocks of pea plants. One parent has blue, axial flowers and the other has white, terminal flowers; all F1 individuals have blue, axial flowers. If you then cross the F1, amongst the F2 offspring, what is the probability of plants with white axial flowers? (Note: The genes for flower colour and location assort independently) O 1/16 O9/16 O 3/16 1/8 O 1/4
- D D 1 2 d In a particular plant, leaf color is controlled by gene locus D. Plants with at least one allele D have dark green leaves, and plants with the homozygous recessive dd genotype have light green leaves. A true-breeding, dark-leaved plant is crossed with a light-leaved one, and the F1 offspring is allowed to self-pollinate. The predicted outcome of the F2 is diagrammed in the Punnett square shown in the figure, where 1, 2, 3, and 4 represent the genotypes corresponding to each box within the square. Which of the boxes marked 1-4 correspond to plants with a heterozygous genotype? O 1 only O 1, 2, and 3 2 and 3 2, 3, and 4 4) 3.We cross two short, non-purple F2 plants. What ratio of the progency will be short and non-purple in the F3 generation? 9/16 16/16 1/16 3/-6Tallness (T) in a certain plant is dominant to short (t), while red (R) flower color is dominant to yellow (r). The heterozygous condition results in orange (Rr) flower color. A short plant with red flowers, is crossed with a plant homozygous for tallness and yellow flowers. What would be the genotype and phenotype of the F1 individuals? ttRr—short and orange ttrr—short and yellow TtRr—tall and red Ttrr—tall and yellow TtRr—tall and orange
- In watermelons, the green colour gene (G) is dominant over the striped colour gene (g), and round shape (R) is dominant over long shape (r). A heterozygous round green colour (GgRr) watermelon plant is crossed with another heterozygous round green colour (GgRr) plant. Determine the expected phenotypic ratio of the F1 generation.The trait of medium-sized leaves in iris is determined by the heterozygous genotype RT. Plants with large leaves are IKIK, whereas plants with small leaves are l'I A cross is made between two plants, each with medium-sized leaves. If they produce 80 seedlings, what would be the expected number of seedlings with small leaves? O a) 0 O b) 20 Oc) 40 Od) 80The self-fertilization of an F1 pea plant produced froma parent plant homozygous for yellow and wrinkledseeds and a parent homozygous for green and roundseeds resulted in a pod containing seven F2 peas. (Yellow and round are dominant.) What is the probability that all seven peas in the pod are yellow and round?
- Let P = purple flowers and p = white, and T = tall plants and t = dwarf. What are the genotypes of the gametes that are produced by a plant that is heterozygous for both traits? hint* This is a dihybrid self cross of an F1 heterozygous generation. O Tt, TT, tt, Pp, PP, and pp P, p, T, and t PT, Pt, pT, and pt PT and ptConsider this cross in pea plants: Tt Rr yy Aa × Tt rr Yy Aa, whereT = tall, t = dwarf, R = round, r = wrinkled, Y = yellow, y = green,A = axial, a = terminal. What is the expected phenotypic outcomeof this cross? Have one group of students solve this problem bymaking one big Punnett square, and have another group solve it bymaking four single-gene Punnett squares and using the multiplication method. Time each other to see who gets done first.Radishes may be long, round, or oval, and they may bered, white, or purple. You cross a long, white variety witha round, red one and obtain an oval, purple F1. TheF2 shows nine phenotypic classes as follows: 9 long, red;15 long, purple; 19 oval, red; 32 oval, purple; 8 long,white; 16 round, purple; 8 round, white; 16 oval, white;and 9 round, red.a. Provide a genetic explanation of these results. Besure to define the genotypes and show the constitutionof the parents, the F1, and the F2.b. Predict the genotypic and phenotypic proportionsin the progeny of a cross between a long, purple radishand an oval, purple one.
