Question

in snapdragons, flower color is controlled by incomplete dominance. the two alleles are red and white. the heterozygous genotype is expressed as pink. cross a pink - flowered plant with a white - flowered plant. what is the probability of producing a pink - flowered plant? 100% 50% 75% 25%

Explanation:

Step1: Define Genotypes

Let \( R \) = red allele, \( W \) = white allele. Pink plant: \( RW \) (heterozygous), White plant: \( WW \) (homozygous recessive).

Step2: Set Up Punnett Square

	\( R \)	\( W \)
\( W \)	\( RW \)	\( WW \)

Step3: Analyze Offspring

From the Punnett square, offspring genotypes: \( RW \) (pink) and \( WW \) (white), each with 2 out of 4 (or 50%) probability.

Answer:

B. 50%
