Question 1:

Cross: Gg (green) × gg (yellow)

Punnett square shown:

```
G g
g Gg gg
g Gg gg
```

Offspring genotypes:
- Top left: Gg → heterozygous
- Top right: gg → homozygous recessive
- Bottom left: Gg → heterozygous
- Bottom right: gg → homozygous recessive

So we have:
- 2 out of 4 = 50% heterozygous (Gg)
- 2 out of 4 = 50% homozygous recessive (gg)

Correct answer: C — 50% heterozygous and 50% homozygous recessive
