Question

wendy crossed two plants that were heterozygous for the trait of flower color. which genotypes could be used to represent the cross?
○ pp, pp
○ pp, pp
○ pp, pp
○ pp, pp

Explanation:

Step1: Recall Mendelian Genetics

When two heterozygous plants (Pp) are crossed, we use a Punnett square. The parents' gametes are P and p for each.

Step2: Construct Punnett Square

	P	p
p	Pp	pp

Step3: Analyze Genotypes from Cross

The possible genotypes of offspring are PP, Pp, and pp. But the question is about the cross of two heterozygous (Pp) plants. Wait, no—wait, the question is "Which genotypes could be used to represent the cross? (two heterozygous plants for flower color)". Wait, heterozygous is Pp, so crossing Pp × Pp. Wait, maybe I misread. Wait, the options: A. Pp × Pp, B. Pp × pp, C. PP × Pp, D. PP × PP? Wait, no, the user's image: the question is "When crossing two plants that were heterozygous for the trait of flower color. Which genotypes could be used to represent the cross?" So heterozygous is Pp, so the cross is Pp × Pp. Wait, let's check the options (from the image, the options are: A. Pp × Pp, B. Pp × pp, C. PP × Pp, D. PP × PP? Wait, no, the image shows options like A. Pp × Pp, B. Pp × pp, C. PP × Pp, D. PP × PP? Wait, no, the original image's options: first option A. Pp × Pp, B. Pp × pp, C. PP × Pp, D. PP × PP? Wait, no, the user's image: the options are (from the text): "A. Pp × Pp", "B. Pp × pp", "C. PP × Pp", "D. PP × PP"? Wait, no, the question is about crossing two heterozygous plants. Heterozygous is Pp, so the cross is Pp × Pp. So the correct option is A. Pp × Pp.

Answer:

A. Pp × Pp
