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. which ratio of red - to - white flowering plants would she expect to see in the phenotypes of the f2 generation? all red 3 red : 1 white 2 red : 2 white 1 red : 3 white

Explanation:

In the Punnett square, genotypes \( Rr \) (red, as \( R \) is dominant) and \( rr \) (white) are present. Counting the number of each phenotype: \( Rr \) (red) appears 2 times and \( rr \) (white) appears 2 times. So the ratio is \( 2:2 \) which simplifies to \( 1:1 \) but looking at the options, the correct way based on dominant - recessive rules (assuming \( R \) is dominant for red and \( r \) is recessive for white) in the given Punnett square (2 \( Rr \) - red and 2 \( rr \) - white) gives a \( 2:2 \) ratio.

Answer:

2 red : 2 white
