Question

a pea plant that has round seeds has the genotype rr. it is crossed with a pea plant that has wrinkled seeds and the genotype rr. what is the probability that the offspring will have wrinkled seeds?
0 percent
25 percent
50 percent
75 percent

Explanation:

Step1: Realizar el cruce genético

El primer padre tiene el genotipo \( Rr \) y el segundo \( rr \). Las gametas del primer padre son \( R \) y \( r \), y las del segundo padre son \( r \) y \( r \).

Step2: Construir la tabla de Punnett

\( R \)\( r \)
\( r \)\( Rr \)\( rr \)

Step3: Calcular la probabilidad

De las cuatro combinaciones posibles en la tabla de Punnett (\( Rr, rr, Rr, rr \)), dos (\( rr \)) corresponden a semillas arrugadas. La probabilidad es \( \frac{2}{4} = 0.5 = 50\%\).

Answer:

50 percent
