in snapdragon flowers petal color is incompletely dominant, the available phenotypes are either pink, white, or red. what is the likelihood of one heterozygous flower and one purebred red flower producing a white offspring?

Explanation:

Step1: Define Genotypes

In incomplete dominance for snapdragon color: let's denote red as \( RR \) (purebred), pink as \( Rr \) (heterozygous), and white as \( rr \). The heterozygous flower is \( Rr \), purebred red is \( RR \).

Step2: Set Up Punnett Square

Cross \( Rr \) (heterozygous) and \( RR \) (purebred red). The possible gametes from \( Rr \) are \( R \) and \( r \); from \( RR \) are \( R \) and \( R \).

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

Step3: Analyze Offspring Genotypes

Offspring genotypes are \( RR \) (red) and \( Rr \) (pink). No \( rr \) (white) genotypes are produced.
