Question details


7. In roses, petal color may be red (R) or white (r) and they may be thornless (T) or have thorns (t). A plant homozygous for all genes that has red petals and thornless is crossed with a plant homozygous for all genes that has white petals and thorns. The FI individuals are intercrossed to produce the F2 generation. a. What is the phenotypic ratio of the F1 generation? b. What is the genotypic ratio of the F2 generation? c. What is the phenotypic ratio of the F2 generation? d. If an FI plant is backcrossed with the red thornless parent, what phenotypes and proportions are expected in their offspring?
