Textbook Question
Chapter 2, Problem 28P

A variety of pea plant called Blue Persian produces a tall plant with blue seeds. A second variety of pea plant called Spanish Dwarf produces a short plant with white seed. The two varieties are crossed, and the resulting seeds are collected. All of the seeds are white; and when planted, they produce all tall plants. These tall F1 plants are allowed to self-fertilize. The results for seed color and plant stature in the F2 generation are as follows:

a. Which phenotypes are dominant, and which are reces-sive? Why?

b. What is the expected distribution of phenotypes in the F2 generation?

c. State the hypothesis being tested in this experiment. d. Examine the data in the table by the chi-square test and determine whether they conform to expectations of the hypothesis.

In tomatoes, tall (D) is dominant over dwarf (d) and smooth fruit (P) is dominant over pubescent fruit (p), which is covered with fine hairs. A farmer has two tall and smooth tomato plants, which we will call plant A and plant B. The farmer crosses plants A and B with the same dwarf and pubescent plant and obtains the following numbers of progeny: Q. Explain why different proportions of progeny are produced when plant A and plant B are crossed with the same dwarf pubescent plant.
You have a pure breeding plant with red flowers, yellow seeds and red-veined leaves. You cross this with another pure breeding plant that has white flowers, pink seeds and yellow leaf veins. All of the offspring (F1) have white flowers, yellow seeds and orange leaf veins. Assuming all three loci are independently assorting, use this information to answer the following question: If two F1 offspring are crossed with each other and 1000 F2 are obtained, approximately how many offspring should have orange leaf veins?   a. 1000   b. 750   c. 500   d. 250   e. Cannot be determined with this information
You self-fertilize an F1 plant to produce the F2 generation.  Based on Mendelian principles of inheritance, what fraction of the F2 generation do you expect to be short with round, green seeds?  HINT:  Solving this problem will require a very large Punnett square (8 x 8), but you can easily solve it using the Multiplication Rule

A farmer has two tall and smooth tomato plants, which we will call plant A and plant B.

If so, what is the rate of recombination between them?
  • In a variety of newly discovered rose plant, flowers are either white or red. Two genes were discovered to control flower color. Both genes, A and B, work in tandem in a biochemical pathway, and dominant forms of both genes are required for red flowers. A doubly-homozygous red-flowered plant is crossed with a doubly-homozygous white-flowered plant. The F1 offspring all have red flowers and are self-crossed to produce the F2. Determine the ratios of phenotypes in the F2 generation.

    A homozygous strain of corn that produces yellow kernels is crossed with another homozygous strain that produces purple kernels.

Give the genotypes of the yellow and purple F2 and propose a genetic model that explains the inheritance of these kernel colors in corn.
