How many of the given traits of garden pea can express itself in heterozygous condition? Green seed, inflated pod, Axial flower position, Dwarf plant height, Yellow pod colour, Round seed shape.

Options

A. Three
B. Four
C. TWO
D. One

Answer

To determine how many of the given traits of garden pea can express themselves in a heterozygous condition, we need to analyze each trait based on its dominance or recessiveness.

### Step-by-Step Solution:

1. **Identify the Traits**: The traits given are:
- Green seed
- Inflated pod
- Axial flower position
- Dwarf plant height
- Yellow pod color
- Round seed shape

2. **Understand Dominance**: In genetics, traits can be either dominant or recessive. A dominant trait will express itself in both homozygous (AA) and heterozygous (Aa) conditions, while a recessive trait will only express itself in a homozygous condition (aa).

3. **Analyze Each Trait**:
- **Green Seed**: This trait is recessive. It will not express itself in a heterozygous condition (Aa).
- **Inflated Pod**: This trait is dominant. It will express itself in both homozygous (AA) and heterozygous (Aa) conditions.
- **Axial Flower Position**: This trait is dominant. It will express itself in both homozygous (AA) and heterozygous (Aa) conditions.
- **Dwarf Plant Height**: This trait is recessive. It will not express itself in a heterozygous condition (Aa).
- **Yellow Pod Color**: This trait is recessive. It will not express itself in a heterozygous condition (Aa).
- **Round Seed Shape**: This trait is dominant. It will express itself in both homozygous (AA) and heterozygous (Aa) conditions.

4. **Count the Traits that can Express in Heterozygous Condition**:
- Inflated pod (dominant)
- Axial flower position (dominant)
- Round seed shape (dominant)

Thus, there are **3 traits** that can express themselves in a heterozygous condition.

### Final Answer:
**3 traits can express themselves in heterozygous condition.**
