Answer:
100%
Step-by-step explanation:
When a homozygous dominant plant (HH) is crossed with a recessive (mild) plant (hh), the offspring will all be heterozygous (Hh) and have the dominant hot flavor allele.
The Punnett square for this cross would be:
| | H | H |
|---|---|---|
| h | Hh | Hh |
| h | Hh | Hh |
As we can see, all of the offspring (100%) will have the dominant H allele and therefore have hot flavor.
Therefore, the correct answer is 100%.
