Answer 1

To help you complete the Punnett squares and information related to Mendel’s pea plants, we will identify the traits you're interested in and provide the statistical outcomes based on typical dihybrid crosses (for two traits at a time).

### 1. **Punnett Square for Flower Color (P = Purple, p = White)**

**Genotypes:**
- **P:** Purple (homozygous dominant or heterozygous)
- **p:** White (homozygous recessive)

**Punnett Square:**
- P x P (both parents homozygous dominant)
- P x p (one homozygous dominant and one heterozygous)
- p x p (both parents homozygous recessive)

For example, if P x p:
```
P p
----------------
P | PP | Pp |
----------------
p | Pp | pp |
----------------
```
- **Outcome:**
- **PP:** 25% (Homozygous Dominant)
- **Pp:** 50% (Heterozygous)
- **pp:** 25% (Homozygous Recessive)

### 2. **Punnett Square for Plant Height (T = Tall, t = Short)**

**Punnett Square:**
- T x T (both homozygous dominant)
- T x t (one homozygous dominant and one heterozygous)
- t x t (both homozygous recessive)

For example, if T x t:
```
T t
----------------
T | TT | Tt |
----------------
t | Tt | tt |
----------------
```
- **Outcome:**
- **TT:** 25% (Homozygous Dominant)
- **Tt:** 50% (Heterozygous)
- **tt:** 25% (Homozygous Recessive)

### 3. **Punnett Square for Seed Shape (S = Round, s = Wrinkled)**

**Punnett Square:**
Assuming both parents are heterozygous:
```
S s
----------------
S | SS | Ss |
----------------
s | Ss | ss |
----------------
```
- **Outcome:**
- **SS:** 25% (Homozygous Dominant)
- **Ss:** 50% (Heterozygous)
- **ss:** 25% (Homozygous Recessive)

### 4. **Punnett Square for Pod Color (G = Green, g = Yellow)**

**Punnett Square:**
Assuming both parents are heterozygous:
```
G g
----------------
G | GG | Gg |
----------------
g | Gg | gg |
----------------
```
- **Outcome:**
- **GG:** 25% (Homozygous Dominant)
- **Gg:** 50% (Heterozygous)
- **gg:** 25% (Homozygous Recessive)

### Summary of Results
- **For Flower Color:**
- Homozygous Dominant (PP): 25%
- Heterozygous (Pp): 50%
- Homozygous Recessive (pp): 25%

- **For Plant Height:**
- Homozygous Dominant (TT): 25%
- Heterozygous (Tt): 50%
- Homozygous Recessive (tt): 25%

- **For Seed Shape:**
- Homozygous Dominant (SS): 25%
- Heterozygous (Ss): 50%
- Homozygous Recessive (ss): 25%

- **For Pod Color:**
- Homozygous Dominant (GG): 25%
- Heterozygous (Gg): 50%
- Homozygous Recessive (gg): 25%

Adjust the ratios according to the specific genotypes of the parents you are working with. If you provide specific genotypes for the crosses you want to analyze, I can assist more precisely!
