A) Describe the data you collect from the Purple 1 x Purple 2 cross. Predict the genotype of each of the parent plants. Explain your predictions using data from the experiment.   B) Consider the offspring, the next generation (F1), from the Purple 1 x Purple 2 cross. What is the probability of a green stem plant? How do you know this?   C) What is the probability in the F2 generation of a green stem offspring? Use a Punnett square(s) and quantitative data to explain your thinking. Upload your Punnett square(s).

The image displays a petri dish containing young seedlings on a moist medium, likely cotton or agar, used for growth. The seedlings exhibit a variety of colors, including green and purple hues. This setup is often used in educational biology experiments to observe plant growth and genetics.

At the bottom of the image, there's a label with the text:

- "pivot interactives" logo

Below the image, there is an interface section showing:

- **PARENT #1**: Purple 2
- **PARENT #2**: Purple 2
- A button labeled "Change"

This suggests an interactive experiment where users can potentially alter parent variables to observe changes in the seedlings.

**72 Hour Seed Disk**

- **Image Description**: The image shows a seed disk with sprouted seeds at the 72-hour mark. Several small seedlings display green leaves and purple stems, with roots visible on the surface.

- **Platform**: Pivot Interactives

- **Options Indicated**: 
  - Parent #1: Purple 1
  - Parent #2: Purple 1
  - Change option available

This setup can be used for educational purposes to study the germination process, observe plant growth, and understand the variables affecting seed development.
