Question
**Title: Analyzing the Expression of lacZ and lacY Genes**

**Description:**

In this exercise, we aim to determine whether the expression of wild-type lacZ and lacY genes would be categorized as "inducible," "uninducible," or "constitutive" in the given examples A and B. 

- **Example A** represents a haploid genotype.
- **Example B** represents a partial diploid genotype.

**Genotype Configurations:**

**A.** \( \text{lacI}^- \, \text{lacO}^+ \, \text{lacZ}^+ \, \text{lacY}^- \)

**B.** 
\( 
\begin{array}{c}
\text{lacI}^- \, \text{lacO}^+ \, \text{lacZ}^- \, \text{lacY}^+ \\
\text{lacI}^+ \, \text{lacO}^+ \, \text{lacZ}^- \, \text{lacY}^+ 
\end{array}
\)

**Interactive Selection:**

For each example, determine whether the expression of lacZ and lacY falls under one of the following categories:
- **constitutive**: The gene is expressed at all times.
- **inducible**: The gene expression is turned on in the presence of an inducer.
- **uninducible**: The gene cannot be expressed, irrespective of the presence of an inducer.

**Example A:**
- LacZ: [Select]
- LacY: [Select]

**Example B:**
- LacZ: [Select]
- LacY: [Select]

By understanding these configurations and classifications, you will gain deeper insights into gene regulation in prokaryotes and how different mutations affect gene expression.
