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?
More Crosses with Pea Plants: The Principle of Independent Assortment Two traits are examined simultaneously in a cross of two pure-breeding pea-plant varieties. Pod shape can be either swollen or pinched. Pea color can be either green or yellow. A plant with the traits swollen and green is crossed with a plant with the traits pinched and yellow, and a resulting F1 plant is self-crossed. A total of 640 F2 progeny are phenotypically categorized as follows: 360 swollen yellow 120 swollen green 120 pinched yellow 40 pinched green a. What is the phenotypic ratio observed for pod shape? Pea color? b. What is the phenotypic ratio observed for both traits considered together? c. What is the dominance relationship for pod shape? Pea color? d. Deduce the genotypes of the P1 and F1 generations.
Sunflowers with flowers 10 cm in diameter are crossed with a plant that has 20-cm flowers. The F1 plants have flowers 15 cm in diameter. In the F2 generation, 4 flowers are 10 cm in diameter and 4 are 20 cm in diameter. Between these are 5 phenotypic classes with diameters intermediate to those at the extremes. a. Assuming that the alleles that contribute to flower diameter act additively, how many genes control flower size in this strain of sunflowers? b. How much does each additive allele contribute to flower diameter? c. What size flower makes up the largest phenotypic class?
Imagine that you are performing a cross involving seed texture in garden pea plants. You cross true-breeding round and wrinkled parents to obtain F1 offspring. Which of the following experimental results in terms of numbers of plants are closest to what you expect in the F2 progeny? a. 8lOroundseeds b. 8lOwrinkledseeds c. 405:395 round seeds:wrinkled seeds d. 610:190 round seeds:wrinkled seeds
A true-breeding pea plant with round and green seeds was crossedto a true-breeding plant with wrinkled and yellow seeds. Roundand yellow seeds are the dominant traits. The F1 plants wereallowed to self-fertilize. What are the following probabilities forthe F2 generation?A. An F2 plant with wrinkled, yellow seeds.B. Three out of three F2 plants with round, yellow seeds.C. Five F2 plants in the following order: two have round, yellowseeds; one has round, green seeds; and two have wrinkled,green seeds.D. An F2 plant will not have round, yellow seeds
Do a punnet square to find the possible genotypes and phenotypes of the F1 generation when a plant that is homozygous recessive for pod color and heterozygous for pea shape is crossed with a plant that is heterozygous for pod color and homozygous dominant for pea shape. Dominant for pod color = G (green) Recessive for pod color = g (yellow) Dominant for pea shape = R (round) Recessive for pea shape = r (wrinkled) P1: GG X Rr Gg X RR
A tall, purple flower plant with genotype Tt Pp is crossed with a tall, white flower plant of genotypeTt pp. What is the probability of obtaining progeny with genotype TTpp? Show your work by using separate punnett square for each trait then multiplying the fractions
You start a cross with a true-breeding red-eyed troll and a true-breeding white-eyed troll, and then cross the F1 offspring to make the F2 generation. In the F2 generation, you collect 3 red-eyed trolls, 8 white-eyed trolls, and 5 pink-eyed trolls. Use a chi-square test to evaluate whether the data matches your expectation if the trait is controlled by a single gene with incomplete dominance. In the spaces below, enter the expected number of offspring in each phenotypic group that you would use to calculate your chi square. Report your expected values to the nearest 0.01. Expected Number of Pink-eyed trolls Expected Number of Red-eyed trolls Expected Number of White-eyed trolls Calculate your chi-square test and answer the following questions: How many degrees of freedom do you have in this test Do you reject the null hypothesis? Yes or no?

In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and disk-shaped fruit (D) is dominant over sphere-shaped fruit (d).. If a squash plant true-breeding for white, disk-shaped fruit is crossed with a plant true-breeding for yellow, sphere-shaped fruit, what will the phenotypic and genotypic ratios be for: a. the F1 generation? b. the F2 generation? You must show the Punnett Square for the F2 generation!
