Question

1. tall pea plants are dominant to short pea plants. a tall pea plant (tt) is crossed with a short pea plant (tt).

Explanation:

Step1: Analyze the genotype probability

From the Punnett square, there are 4 offspring genotypes. The number of TT is 0, the number of Tt is 4, and the number of tt is 0.
The probability of TT: $\frac{0}{4}\times100\% = 0\%$
The probability of Tt: $\frac{4}{4}\times100\% = 100\%$
The probability of tt: $\frac{0}{4}\times100\% = 0\%$

Step2: Analyze the phenotype probability

Since tall (T) is dominant over short (t), plants with genotype Tt will be tall.
The probability of tall pea plants (phenotype): $\frac{4}{4}\times100\% = 100\%$
The probability of short pea plants (phenotype): $\frac{0}{4}\times100\% = 0\%$

Answer:

Genotype Probability (\%):
TT: \(0\%\)
Tt: \(100\%\)
tt: \(0\%\)

Phenotype Probability (\%):
Tall Pea Plant: \(100\%\)
Short Pea Plant: \(0\%\)
