In a particular species of flowering plant, tall is dominant to short, and flowers with red petals are dominant to flowers with white petals. A tall plant with white flowers (homozygous for both traits) is crossed with a tall plant with red flower (heterozygous for both traits). Show the cross and answer the following a) What will be the genotypes of the parents? b) What are the phenotypic and phenotypic ratios of F1 generation?
Dear student,
Please find below the solution to the asked query
Parent generation: TTrr (tall and white) × TtRr (tall and red)
Gamete : Tr TR, tr, tR, Tr
F1 generation:
Phenotypes: 50% (Tall and red - TTRr, TtRr), 50% (tall and white - TTrr, Ttrr).
Ratio: 1 (tall and red):1 (tall and white).
Please find below the solution to the asked query
Parent generation: TTrr (tall and white) × TtRr (tall and red)
Gamete : Tr TR, tr, tR, Tr
F1 generation:
| TR | tR | Tr | tr | |
| Tr | TTRr | TtRr | TTrr | Ttrr |
Phenotypes: 50% (Tall and red - TTRr, TtRr), 50% (tall and white - TTrr, Ttrr).
Ratio: 1 (tall and red):1 (tall and white).
