Chapter 14, Problem 10TYK

A true-breeding dwarf corn plant with red ears is mated to a true-breeding tall corn plant with yellow ears. The F1 generation is self-pollinated, and in the F2 generation the following offspring appear: 10 tall red-eared plants, 30 dwarf red-eared plants, 90 dwarf yellow-eared plants, 30 tall yellow-eared plants. Which of the following statements is true?

  1. a. Tall and red are both dominant.
  2. b. Tall and yellow are both dominant.
  3. c. Dwarf and red are both dominant.
  4. d. Dwarf and yellow are both dominant.

In tomatoes, the red fruit color is completely dominant to yellow. Suppose a tomato plant homozygous for red is crossed with one homozygous for yellow and the progeny are allowed to self pollinate. What phenotypes do you predict in the F2 generation?   a) 3 red: 1 yellow   b) 9 red : 3 orange : 1 yellow    c) 1 red : 2 orange : 1 yellow   d) 1 red : 1 yellow
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!
A heterozygous pea plant that is tall with yellow seeds, TtGg, is allowed to self-fertilize.   What is the probability that an offspring will be either tall with yellow seeds, tall with green seeds or dwarf with yellow seeds? Use the Sum Rule to calculate the probability asked in the problem.
