Answer:

To predict the offspring based on the type of inheritance using a Punnett square, we need to determine the possible genotypes of both parents. Since both parents are heterozygous for leaf color, their genotypes would be:

Parent 1: Gg (green allele from one parent and yellow allele from the other)

Parent 2: Gg (same genotype as Parent 1)

Now, let's create a Punnett square to show the possible combinations of alleles in their offspring:

```

| G | g |

------------------------------

G | GG | Gg |

------------------------------

g | Gg | gg |

```

In the Punnett square, the capital letters represent the dominant allele for green color (G), and the lowercase letters represent the recessive allele for yellow color (g).

From the Punnett square, we can see that there are three possible genotypes in the offspring:

1. GG: This genotype represents the offspring inheriting the dominant allele (G) from both parents. The individual will have green leaf color.

2. Gg: This genotype represents the offspring inheriting one dominant allele (G) and one recessive allele (g) from the parents. The individual will also have green leaf color because the dominant allele overrides the recessive allele.

3. gg: This genotype represents the offspring inheriting the recessive allele (g) from both parents. The individual will have yellow leaf color because the recessive allele is expressed.

In summary, the possible offspring genotypes for leaf color based on the type of inheritance are GG (green), Gg (green), and gg (yellow).
