Hint: Draw a Punnett Square to help you with this question.

In a genetics laboratory, a heterozygous tall plant (Tt) is crossed with a homozygous short plant (tt). If tall (T) is dominant over short (t), what are the expected phenotypic results? what is the percentage for tall and short.
Tall: 0%, 25%, 50%, 75%, 100%,
Short: 0%, 25%, 50%, 75%, 100%

The Punnett square for this cross would be:

T t
T TT Tt
t Tt tt

Therefore, the expected phenotypic results are:
- 50% tall (Tt)
- 50% short (tt)

So, the percentage for tall would be 50% and the percentage for short would also be 50%.
