The set pollinated progeny of a homozygous plant constitues a

Options

A. pure line
B. mass selection
C. mixed population
D. heterosis

Answer

To solve the question, "The set pollinated progeny of a homozygous plant constitutes a," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Homozygosity**:
- A homozygous plant has two identical alleles for a particular trait. This means that when it undergoes self-pollination, all the offspring will inherit the same alleles from the parent.

2. **Definition of Progeny**:
- Progeny refers to the offspring or descendants of a particular organism. In this case, we are looking at the offspring produced from a homozygous plant through self-pollination.

3. **Result of Self-Pollination**:
- When a homozygous plant self-pollinates, it produces progeny that are genetically identical to the parent plant. This results in a uniform set of traits in the offspring.

4. **Terminology**:
- The progeny produced from a homozygous plant through self-pollination is often referred to as a "pure line." This term indicates that the progeny are genetically uniform and stable, maintaining the traits of the parent plant.

5. **Conclusion**:
- Therefore, the answer to the question is that the set pollinated progeny of a homozygous plant constitutes a "pure line."

### Final Answer:
The set pollinated progeny of a homozygous plant constitutes a **pure line**.
