Textbook Question
Textbook QuestionTwo pure-breeding wheat strains, one producing dark red kernels and the other producing white kernels, are crossed to produce F₁ with pink kernel color. When an F₁ plant is self-fertilized and its seed collected and planted, the resulting F₂ consist of 160 plants with kernel colors as shown in the following table. Kernel Color Number White 9 Dark red 12 Red 39 Light pink 41 Pink 59 If an F₁ plant is crossed to a dark red plant, what are the expected progeny phenotypes and what is the expected proportion of each phenotype?
