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%.
