Question

in pea plants, tallness (t) is dominant to shortness (t). what are the predicted percentages of the genotypes of the offspring if a homozygous short plant is crossed with a heterozygous tall plant?
● 25 percent tt, 75 percent tt
● 25 percent tall, 75 percent short
● 50 percent tt, 50 percent tt
● 50 percent tall, 50 percent short

Explanation:

Step1: Determinar los genotipos de los padres

El genotipo del padre homocigoto corto es \( tt \). El genotipo del padre heterocigoto alto es \( Tt \).

Step2: Realizar el cruce

\( T \)\( t \)
\( t \)\( Tt \)\( tt \)

Step3: Calcular las proporciones

Hay dos \( Tt \) y dos \( tt \) en el cuadro de Punnett. Entonces, la proporción de \( Tt \) es \( \frac{2}{4} = 50\% \) y la proporción de \( tt \) es \( \frac{2}{4} = 50\% \).

Answer:

C. 50 percent Tt, 50 percent tt
