A cross between a homozygous recessive and a heterozygous plant is called

Options

A. Linkage cross
B. Reciprocal cross
C. Test cross
D. Monohybrid cross

Explanation

To solve the question "A cross between a homozygous recessive and a heterozygous plant is called", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Homozygous Recessive**: This refers to an organism that has two identical recessive alleles for a trait (e.g., "tt").
- **Heterozygous**: This refers to an organism that has one dominant and one recessive allele for a trait (e.g., "Tt").

2. **Identify the Cross**:
- In this scenario, we are crossing a homozygous recessive plant (tt) with a heterozygous plant (Tt).

3. **Define the Purpose of the Cross**:
- The purpose of this cross is to determine the genotype of the heterozygous plant. By crossing it with a homozygous recessive plant, we can observe the offspring's phenotypes.

4. **Recognize the Type of Cross**:
- This specific type of cross is known as a **Test Cross**. A test cross is used to determine whether an individual with a dominant phenotype is homozygous or heterozygous.

5. **Conclude the Answer**:
- Therefore, the answer to the question is that a cross between a homozygous recessive and a heterozygous plant is called a **Test Cross**.

### Final Answer:
A cross between a homozygous recessive and a heterozygous plant is called a **Test Cross**.
