Question

The dominant trait for pea pod color is Green (G), while the recessive trait is yellow (g). If we have 2 heterozygous Green pea pods (Gg), what is the probability their offspring will be yellow (gg)? A Punnett square has been provided below.

Answer 1

To find the probability of the offspring being yellow (gg) from two heterozygous Green pea pods (Gg), we can use a Punnett square.

The possible gametes from each parent (both Gg) are:

- G (dominant)
- g (recessive)

Setting up a Punnett square, we have:

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

From the Punnett square:

- 1 GG (green)
- 2 Gg (green)
- 1 gg (yellow)

This gives us a total of 4 possibilities:

- 3 out of 4 combinations result in green (GG or Gg)
- 1 out of 4 combinations results in yellow (gg)

Thus, the probability that their offspring will be yellow (gg) is:

\[ \frac{1}{4} = 25\% \]

So, the answer is **25%**.
