Question
As in the plants of Problem $6,$ color may be red, white, or pink; and flower shape may be personate or peloric. Determine the $\mathrm{P}_{1}$ and $\mathrm{P}_{1}$, genotypes for the following crosses:
Step 1
- Pink color is produced by the heterozygous genotype (Rr). - Personate shape (P) is dominant over peloric shape (p). Now, let's determine the P1 and P2 genotypes for each cross: Show more…

As in the plants of Problem $6,$ color may be red, white, or pink and flower shape may be personate or peloric. Determine the $\mathrm{P}_{1}$ and $\mathrm{F}_{1}$ genotypes for the following crosses: (a) red, peloric $\times$ white, personate $\mathrm{F}_{1}:$ all pink, personate (b) red, personate $\times$ white, peloric $\mathrm{F}_{1}:$ all pink, personate (c) pink, personate $\times$ red, peloric $F_{1:}\left\{\begin{array}{l}1 / 4 \text { red, personate } \\ 1 / 4 \text { red, peloric } \\ 1 / 4 \text { pink, personate } \\ 1 / 4 \text { pink, peloric }\end{array}\right.$ (d) pink, personate $x$ white, peloric $\mathbf{F}_{1:}\left\{\begin{array}{l}1 / 4 \text { white, personate } \\ 1 / 4 \text { white, peloric } \\ 1 / 4 \text { pink, personate } \\ 1 / 4 \text { pink, peloric }\end{array}\right.$ (e) What phenotypic ratios woud result from crossing the $\mathrm{F}_{1}$ of (a) to the $F_{1}$ of $(b) ?$
Pea flowers may be purple (P) or white (p). Pea seeds may be round (R) or wrinkled (r). What proportion of the offspring from the cross ppRr x PpRR will have purple flowers and round seeds? Remember that capital letters indicate a dominant trait.
