The correct Answer is:
To determine how many different kinds of gametes will be produced by a plant with the genotype AABbCCddEEff, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Genotype**: The given genotype is AABbCCddEEff. 2. **Classify Each Locus**: - **AA**: Homozygous (both alleles are the same) - **Bb**: Heterozygous (alleles are different) - **CC**: Homozygous - **dd**: Homozygous - **EE**: Homozygous - **ff**: Homozygous 3. **Count the Heterozygous Loci**: - From the classification, we see that only **Bb** is heterozygous. - Therefore, there is **1 heterozygous locus**. 4. **Use the Formula for Gametes**: - The formula to calculate the number of different gametes is \(2^n\), where \(n\) is the number of heterozygous loci. - Here, \(n = 1\). 5. **Calculate the Number of Gametes**: - Substitute \(n\) into the formula: \[ 2^1 = 2 \] - Therefore, the plant will produce **2 different kinds of gametes**. 6. **List the Gametes**: - The two types of gametes can be derived from the heterozygous locus (Bb): - **Gamete 1**: A, B, C, d, E, f (from AABbCCddEEff) - **Gamete 2**: A, b, C, d, E, f (from AABbCCddEEff) - The only difference is in the B allele. ### Final Answer: The plant with the genotype AABbCCddEEff will produce **2 different kinds of gametes**. ---
