Question

flowers (pp).
which genotypes will be included for the offspring in the punnett square for this cross?
○ pp, pp, and pp
○ pp and pp
○ pp and pp
○ pp only

Explanation:

Step1: Identify parent genotypes

The problem states one parent is purple flowers (PP, homozygous dominant) and the other is white flowers (pp, homozygous recessive).

Step2: Determine gametes for each parent

PP parent produces only P gametes; pp parent produces only p gametes.

Step3: Set up Punnett square

Cross P gametes with p gametes:

$$\begin{array}{c|c} & P \\ \hline p & Pp \\ \end{array}$$

All offspring inherit one P and one p allele.

Answer:

Pp only
