Question

incomplete dominance problems

1. in snapdragons, flower color is controlled by incomplete dominance. the two alleles are red (r) and white (r). the heterozygous genotype is expressed as pink.

a. what is the phenotype of a plant with the genotype rr?
b. what is the phenotype of a plant with the genotype rr?
c. what is the phenotype of a plant with the genotype rr?

1. a pink - flowered plant is crossed with a white - flowered plant. what is the probability of producing a pink - flowered plant?%

Explanation:

Step1: Determinar los genotipos de los padres

Un planta de color rosa tiene el genotipo \( Rr \) (ya que en dominancia incompleta \( Rr \) es rosa), y una planta blanca tiene el genotipo \( rr \).

Step2: Realizar el cruce (tabla de Punnett)

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

Step3: Calcular la probabilidad

De los 4 posibles descendientes, 2 tienen el genotipo \( Rr \) (rosa). La probabilidad es \( \frac{2}{4}=\frac{1}{2} = 50\%\)

Answer:

50
