When a cross is made between a tall plant with yellow seeds (Tt Yy) and a tall plant with green seeds (Tt yy), what is true regarding the proportions of phenotypes of the offsprings in `F_(1)` generation ?

Options

A. `{:("Proportion of Tall and Green proportion of Dwarf and Green"),( (3)/(8)" "(1)/(8)):}`
B. `{:("Proportion of Tall and Green proportion of Dwarf and Green"),( (2)/(8)" "(1)/(8)):}`
C. `{:("Proportion of Tall and Green proportion of Dwarf and Green"),( (1)/(8)" "(3)/(8)):}`
D. `{:("Proportion of Tall and Green proportion of Dwarf and Green"),( (2)/(8)" "(2)/(8)):}`

Explanation

To solve the problem of determining the proportions of phenotypes in the F1 generation from the cross between a tall plant with yellow seeds (Tt Yy) and a tall plant with green seeds (Tt yy), we will follow these steps:

### Step 1: Identify the Genotypes of the Parents
The genotypes of the two parent plants are:
- Parent 1: Tt Yy (tall with yellow seeds)
- Parent 2: Tt yy (tall with green seeds)

### Step 2: Determine the Gametes
Next, we need to determine the possible gametes that each parent can produce.
- Parent 1 (Tt Yy) can produce the gametes: TY, Ty, tY, ty
- Parent 2 (Tt yy) can produce the gametes: Ty, ty

### Step 3: Set Up a Punnett Square
Now we will set up a Punnett square to combine the gametes from both parents.

```
| Ty | ty |
---------------------------
TY | TTYy | TTYy |
---------------------------
Ty | TtYy | Ttyy |
---------------------------
tY | TtYy | ttyy |
---------------------------
ty | Ttyy | ttyy |
```

### Step 4: Fill in the Punnett Square
From the combinations in the Punnett square, we can identify the resulting genotypes:
- TTYy (tall, yellow)
- TtYy (tall, yellow)
- Ttyy (tall, green)
- ttyy (dwarf, green)

### Step 5: Determine the Phenotypes
Now we will classify these genotypes into phenotypes:
1. TTYy - Tall, Yellow
2. TtYy - Tall, Yellow
3. Ttyy - Tall, Green
4. ttyy - Dwarf, Green

### Step 6: Count the Phenotypes
Now we will count the number of each phenotype:
- Tall, Yellow: 2 (TTYy and TtYy)
- Tall, Green: 1 (Ttyy)
- Dwarf, Green: 1 (ttyy)

### Step 7: Calculate the Proportions
Now, we can calculate the proportions of each phenotype:
- Tall, Yellow: 2 out of 4 (or 2/4 = 1/2)
- Tall, Green: 1 out of 4 (or 1/4)
- Dwarf, Green: 1 out of 4 (or 1/4)

### Conclusion
The proportions of phenotypes in the F1 generation are:
- Tall, Yellow: 1/2
- Tall, Green: 1/4
- Dwarf, Green: 1/4
