Question

no additional details were added for this assignment.
the horticulturalist crosses two geraniums from the f1 generation.
look at the punnett square to see this cross.

	r	r
r	rr	rr

which ratio of red - to - white flowering plants would she expect to see in the phenotypes of the f2 generation?

• all red
• 1 red : 3 white
• 3 red : 1 white
• 2 red : 2 white

Explanation:

Step1: Determine Genotypes and Phenotypes

From the Punnett square, the genotypes are \( RR \), \( Rr \), \( Rr \), and \( rr \). Assuming \( R \) is dominant (red) and \( r \) is recessive (white), \( RR \) and \( Rr \) show the red phenotype, and \( rr \) shows the white phenotype.

Step2: Count Phenotypes

Count red - producing genotypes: \( RR \) (1), \( Rr \) (2) → total 3 red - phenotyped plants. Count white - producing genotype: \( rr \) (1) → 1 white - phenotyped plant.

Answer:

3 red : 1 white
