Answer:

3rd choice

Explanation:

When creating a Punnett square, one parent's alleles are written across the top of the square and the other parent's alleles are written down the left side. Then, the predicted genes of the offspring are written inside the grid like a multiplication table.

Punnett squares correctly represent the possible offspring resulting from this cross in the given cross - Gg with gg (the third Punnett square)

Punnett square

Let us have G be the dominant yellow allele and g be the recessive green allele. From the information that we have established above, the parent's genotypes are Gg and gg.

The Punnett square involves drawing a two-by-two box. The first parent's alleles will be on top of the box with one letter in each column. The other parent's alleles will be placed on the left side of the box with one letter in each row.

Each box within the square represents 25% of your population.
