In squash, the allele for white fruit (W) is dominant over the allele for yellow (w). If a white fruit plant is crossed with a yellow fruit plant and all the offspring are yellow, what are the possible genotypes of the parents and the offspring? Show the Punnett square.

**Parents:**
- White fruit plant: Ww (heterozygous)
- Yellow fruit plant: ww (homozygous recessive)

**Offspring:**
- All offspring are yellow: ww

**Punnett Square:**

| | w | w |
|---|---|---|
| W | Ww | Ww |
| w | ww | ww |

- Result: 50% Ww (white), 50% ww (yellow)

**Conclusion:**
Since all offspring are yellow, the white fruit parent must have been heterozygous (Ww) to produce yellow offspring (ww) with the yellow fruit parent (ww).

Answer :

Answer:

Well the white allele had to be Ww.

Explanation:

So you cross them and you 50% white and 50% yellow if the white parent was Ww.
