A plant may have green, white, or green-and-white (variegated) leaves on its branches, owing to a mutation in the chloroplast that prevents color from developing. Predict the results of the following crosses: Ovule Source Pollen Source (a) Green branch * White branch (b) White branch * Green branch (c) Variegated branch * Green branch (d) Green branch * Variegated branch

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?
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? What genotypes and phenotypes will be produced in the F2 generation?
In corn, the allele f ′ causes floury endosperm and the allele f ″ causes flinty endosperm. In the cross f ′/f ′ ×f ″/f ″, all the progeny endosperms are floury, but, in the reciprocal cross, all the progeny endosperms are flinty. What is a possible explanation? (Check the legend for Figure 2-7.)
A white F2 plant is allowed to self-fertilize. Of the progeny, 3/4 are white-flowered, and 1/4 are purple-flowered. What is the genotype of the white F2 plant?
In Mendelfruit plants, fruit may be either round (RR), long (rr) or oval (Rr). Cross two oval-fruit plants. What is the phenotypic ratio of the resulting offspring? (what do they LOOK LIKE?) Cross a round-fruit plant and an oval-fruit plant. Give the phenotypic ratio of the offspring.
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.
Imagine you are crossing two plants that have these two genotypes—Tt and tt. What are the two genotypes of the gametes that the Tt plant can make? What is the one genotype of the gametes that the tt plant can make? Set up a Punnett square to analyze the cross. Does the Punnett square need to have four boxes or just two? If you were crossing a TT plant with a tt plant, how many boxes would be necessary in a Punnett square?
. Figure shows the results of a dihybrid cross involving seed shape and seed color. Q. What proportion of the round and yellow F2 progeny from this cross is homozygous at both loci?
A cross is made between a pea plant that is RrYy and one that isrrYy. What is the predicted outcome of the seed phenotypes?a. 9 round, yellow : 3 round, green : 3 wrinkled, yellow :1 wrinkled, greenb. 3 round, yellow : 3 round, green : 1 wrinkled, yellow :1 wrinkled, green c. 3 round, yellow : 1 round, green : 3 wrinkled, yellow :1 wrinkled, greend. 1 round, yellow : 1 round, green : 1 wrinkled, yellow :1 wrinkled, green
Why is it impossible to cross a green and an albino plant?
Suppose Melissa started growing four o'clock plants, Mirabilis jalapa, in her garden. She noticed that the plants have white, green, or patchy white and green (variegated) leaves. Melissa would like to have only four o'clock plants with variegated leaves, so she crosses a few of her plants to see which crosses produce offspring with variegated leaves. She knows that leaf color is determined by the color of the chloroplasts. For each cross, determine the offspring phenotypes that could be observed. Each cross may produce plants with one or more different phenotypes. Parent crosses Offspring phenotypes green female × green male white female × variegated male variegated female × green male variegated female × white male
. What is the basis for the green-and-white color variegation in the leaves of Mirabilis? If the following cross ismade,variegated / × green what progeny types can be predicted? What about thereciprocal cross?
