Question

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. (Again, you may need to use data from other crosses!)

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).

Transcribed Image Text:**Title: Seed Germination Observation** **Image Description:** The image shows a close-up of a seed disk that has been observed for 72 hours. The seeds are placed on a moist paper within a dish, displaying visible signs of germination. Tiny roots, or radicles, have begun to emerge from the seeds, indicating early stages of growth. **Additional Information:** In the bottom-left corner, there is a logo and label: "Pivot Interactives." This suggests the experiment might be part of an interactive learning module. **Interface Elements:** - There are control buttons at the bottom indicating playback options, such as play, pause, and skip. - A button labeled “Change” is located between two parameters: Parent 1 (Purple 1) and Parent 2 (Purple 2), possibly for comparison or analysis tools related to the experiment. **Educational Context:** This setup is ideal for studying the germination process, observing how seeds develop roots, and understanding factors that contribute to successful seed growth.

**72 Hour Seed Disk Observation**

This image shows seedlings after 72 hours of growth on a seed disk. The seedlings display various stages of development, indicating early germination. The primary features include small green leaves and purple stems, characteristic of young plants.

**Diagram Explanation:**

- **Seedlings**: Visible growth includes cotyledons, which are the first leaves that emerge from a germinating seed. They have a vibrant green color.
- **Stems**: The stems exhibit a purplish hue and are slightly curved, a common trait in young seedlings as they acclimate to their environment.

**Platform and Controls:**

- This image is from Pivot Interactives, a platform that allows for interactive educational content.
- At the bottom of the screen, controls are available for interacting with the content, including playback buttons labeled "PARENT A1: Purple 1," "PARENT A2: Purple 2," and a "Change" button, possibly to switch between different views or datasets.
