A true breeding plant is

Options

A. Always homozygous recessive in its genetic constitution
B. One that is able to breed on its own
C. Produced due to cross pollination among unrelated plants
D. Near homozygous and produces offspring of its own kind

Answer

### Step-by-Step Solution:

1. **Definition of True Breeding Plants**:
A true breeding plant is defined as a plant that consistently produces offspring with the same traits when self-pollinated or crossed with another true breeding plant of the same trait. This means that the genetic makeup of the plant is stable and predictable.

2. **Genetic Constitution**:
True breeding plants are always homozygous for the traits they express. This means that they have two identical alleles for a particular gene (e.g., TT for tall plants or tt for short plants).

3. **Reproduction**:
True breeding plants can reproduce on their own through self-pollination. When they do, they pass on the same alleles to their offspring, ensuring that the offspring have the same phenotype as the parent.

4. **Preservation of Traits**:
True breeding plants preserve their traits over generations. For example, if a true breeding plant is tall, all its offspring will also be tall, demonstrating the stability of the trait.

5. **Contrast with Non-True Breeding Plants**:
If a plant is heterozygous (e.g., Tt), it may produce offspring with different traits (some tall and some short), which means it does not qualify as a true breeding plant.

6. **Conclusion**:
Therefore, a true breeding plant is always homozygous and produces offspring of its own kind, maintaining the same traits across generations.
