For the following synopsis, fill in your answers in the Punnett Square drawn below for each of the two F2 purple seedlings. Suppose that instead of being ground up, your seedling had been allowed to grow into a plant and then be cross-pollinated with a plant with the genotype ANL/gnl, F2 purple #1 allele 1 result goes here allele 2 result goes here ANL Anl F2 purple #2| allele 1 result goes here | allele 2 result goes here ANL Anl,

**Title:** Understanding Punnett Squares in Genetic Crosses

**Introduction**
In this activity, you'll explore how to predict the genetic outcomes of cross-pollination in plants using a Punnett Square. This exercise focuses on two F2 purple seedlings that have been cross-pollinated with a plant of genotype ANL/anl.

**Instructions:**
For each of the two F2 purple seedlings, fill in the Punnett Square provided to determine the genetic combinations.

**Scenario:**
Suppose your seedling was allowed to grow into a mature plant and cross-pollinate with a plant having the genotype ANL/anl.

**Punnett Square for F2 purple #1:**

|         | allele 1 result goes here | allele 2 result goes here |
|---------|----------------------------|----------------------------|
| **ANL** |                            |                            |
| **Anl** |                            |                            |

**Punnett Square for F2 purple #2:**

|         | allele 1 result goes here | allele 2 result goes here |
|---------|----------------------------|----------------------------|
| **ANL** |                            |                            |
| **Anl** |                            |                            |

**Diagram Explanation:**
Each Punnett Square is a grid used to predict the genetic makeup resulting from a particular genetic cross. Each box within the grid represents a possible genotype for the offspring. Here, "ANL" and "Anl" represent the alleles from each seedling being crossed with the ANL/anl plant.

Use these tables to fill in the potential outcomes based on this genetic cross. This exercise will help you understand how genetic traits are inherited and expressed in offspring.
