![**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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa6c5565a-787b-43d3-b23e-780453faf6da%2Feb837b67-718a-4c12-829e-620c7a597288%2F0ywhraq_processed.png&w=3840&q=75)
