A test is performed to known whether the given plant is homozygous dominant or heterozygous. Name the test and phenotypic ratio of this test for a monohybrid cross.

Explanation

To determine whether a given plant is homozygous dominant or heterozygous, we can perform a specific genetic test known as a **test cross**. Here’s a step-by-step solution to the question:

### Step-by-Step Solution:

1. **Understanding the Phenotype**:
- The plant in question exhibits a dominant phenotype (e.g., tall). However, we need to determine its genotype, which could either be homozygous dominant (TT) or heterozygous (Tt).

2. **Performing a Test Cross**:
...
