A white pea plant is crossed a heterozygous violet pea plant. What will be characteristic of offspring .

Options

A. 75% recessive
B. 50% recessive
C. 25% recessive
D. All dominant

Answer

To solve the problem of determining the characteristics of the offspring from a cross between a white pea plant and a heterozygous violet pea plant, we can follow these steps:

### Step 1: Identify the Traits
- **White flower color** is a recessive trait, denoted as **"w"**.
- **Violet flower color** is a dominant trait, denoted as **"W"**.

### Step 2: Determine the Genotypes
- The white pea plant will have the genotype **"ww"** (homozygous recessive).
- The heterozygous violet pea plant will have the genotype **"Ww"** (one dominant allele and one recessive allele).

### Step 3: Set Up the Punnett Square
We can set up a Punnett square to visualize the possible offspring from this cross:

```
W w
__________
w | Ww | ww |
__________
```

### Step 4: Analyze the Offspring
From the Punnett square, we can see the possible combinations of alleles for the offspring:
- **Ww** (Violet flower) - 50% of the offspring
- **ww** (White flower) - 50% of the offspring

### Step 5: Conclusion
The characteristics of the offspring will be:
- 50% of the offspring will have violet flowers (dominant trait).
- 50% of the offspring will have white flowers (recessive trait).

### Final Answer
The correct answer is **50% recessive** (option B).
