Chapter 4, Problem 13PDQ

As in Problem 12, flower color may be red, white, or pink, and flower shape may be personate or peloric. For the following crosses, determine the P₁ and F₁ genotypes:

1. (a) red, peloric × white, personate

   ↓

  F1: all pink, personate

1. (b) red, personate × white, peloric

   ↓

  F1: all pink, personate

(c) $\text{pink, personate }\times \text{ red, peloric }\to {\text{F}}_{\text{1}}\{\begin{array}{l}\text{1/ 4 red, personate}\\ \text{1/ 4 red, peloric}\\ \text{1/ 4 pink, peloric}\\ \text{1/ 4 pink, personate}\end{array}$

(d) $\text{pink, personate }\times \text{ white, peloric }\to {\text{F}}_{\text{1}}\{\begin{array}{l}\text{1/ 4 white, personate}\\ \text{1/ 4 white, peloric}\\ \text{1/ 4 pink, personate}\\ \text{1/ 4 pink, peloric}\end{array}$

(c) What phenotypic ratios would result from crossing the F₁ of (a) to the F₁ of (b)?
