- 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 ptA pea plant is heterozygous for three genes (Tt Rr Yy), whereT = tall, t = dwarf, R = round seeds, r = wrinkled seeds, Y = yellowseeds, and y = green seeds. Tall, round, and yellow are the dominanttraits. What is the probability that an offspring from self-fertilizationof this plant will be tall with wrinkled, yellow seeds?Consider this four-factor cross: 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 probability that the first three plantswill have round seeds? What is the easiest way to solve this problem?
- Consider 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.If an incompletely dominant red-flowered plant is crossed with an incompletely dominant white-flowered plant, what are the genotypes and phenotypes of the plant F1 generation?

- F2 Cross: Tall, White, Axial x Dwarf, Violet, Terminal DdwwAA x ddWWaa Character: Stem height, Flower color & position Use fork-line method to check the possible offspring. Show and interpret all the possible genotypes and phenotypes of the offsprings.A male plant with genotype AaBBCcDdee was crossed with one heterozygous for all thegenes. (a) what is the probability of getting a pollen with ABcDe genes? (b) of producing anovum with three dominant and two recessive genes? (c) of getting a progeny with samephenotype as the female parent? (d) of progeny with exactly same genotype as the femaleparent? (e) If instead of the above male, the cross was with one heterozygous for all thegenes, what proportion of the offspring will have three dominant phenotypic traits. (f) willbe genotypically like the parents?In corn, male sterility is controlled by maternal cytoplasmic elements. This phenotype renders the male part of corn plants (i.e. the tassel) unable to produce fertile pollen; the female parts, however, remain receptive to pollination by pollen from male-fertile corn plants. However, the presence of a nuclear fertility restorer gene F restores fertility to male-sterile lines. Using the following color-coded circles, simulate the crosses indicated below. Put the illustrations of crosses in the spaces provided. Be sure to include in the labels the genotypes and phenotypes of the offspring in each cross. Big light green circle - male-sterile cytoplasm Big orange circle - male-fertile cytoplasm Small orange circle - FF nucleus Small half-light green-half-orange circle - Ff nucleus Small light-green circle - ff nucleus
