Question

question 2 points 2
if a tall plant (tt) is crossed with a short plant (tt), what percentage of the offspring will be short?
0%
25%
75%
100%

Explanation:

Step1: Identify parent gametes

Tall plant (TT) produces only $T$ gametes; short plant (tt) produces only $t$ gametes.

Step2: Predict offspring genotypes

All offspring inherit one $T$ and one $t$, so genotype is $Tt$.

Step3: Determine phenotype expression

The $T$ (tall) allele is dominant, so all $Tt$ offspring are tall. Short phenotype requires $tt$ genotype, which is not present.

Step4: Calculate short offspring percentage

$\frac{0}{4} \times 100\% = 0\%$

Answer:

0%
