A gene that masks another genes expression is called

Options

A. Dominant characters
B. Recessive characters
C. Epistatic
D. Assorted

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term used to describe a gene that masks the expression of another gene. This is a fundamental concept in genetics.

2. **Analyzing the Options**:
- **Option 1: Dominant Characters**: Dominant characters are traits that are expressed when at least one dominant allele is present. They do not necessarily mask another gene's expression.
- **Option 2: Recessive Characters**: Recessive characters are traits that are expressed only when the genotype is homozygous recessive. They do not mask other genes.
- **Option 3: Epistatic**: This term refers to a gene that can mask or suppress the expression of another gene. This is a key concept in gene interaction.
- **Option 4: Assorted**: This term refers to the independent assortment of genes during gamete formation and does not relate to masking gene expression.

3. **Identifying the Correct Answer**: Based on the definitions and explanations of each option, the term that describes a gene that masks the expression of another gene is "epistatic."

4. **Defining Epistatic Gene**: An epistatic gene is one that masks the phenotypic effect of another gene, which is referred to as the hypostatic gene. This interaction is crucial in understanding genetic traits and inheritance patterns.

5. **Conclusion**: Therefore, the correct answer to the question is **Option 3: Epistatic**.
