Question

Punnet square: green peas are dominant over yellow peas. G=green g=yellow. Place the correct genotypes in the punnet square below

Answer 1

To create a Punnett square for the peas in question, let's clarify the genotypes involved:

- The dominant allele for green peas is represented by "G".
- The recessive allele for yellow peas is represented by "g".

If we are crossing two pea plants, the genotype of each parent must be determined. Here are three scenarios you might consider:

1. **Homozygous Dominant (GG) x Homozygous Recessive (gg)**

```
G | G
-----------------
g | Gg | Gg |
-----------------
g | Gg | Gg |
```

This would result in all green peas (Gg).

2. **Heterozygous (Gg) x Homozygous Recessive (gg)**

```
G | g
-----------------
g | Gg | gg |
-----------------
g | Gg | gg |
```

This would result in a 50% chance of green peas (Gg) and a 50% chance of yellow peas (gg).

3. **Heterozygous (Gg) x Heterozygous (Gg)**

```
G | g
-----------------
G | GG | Gg |
-----------------
g | Gg | gg |
```

This would yield a ratio of 25% GG (green), 50% Gg (green), and 25% gg (yellow), or a 75% chance of green peas and a 25% chance of yellow peas.

Please specify the genotypes of the parent plants you want to use so I can create the corresponding Punnett square!
