Question

phenotype and genotype of the F1 generation is a plant bearing bearing pure axial flower is crossed with the plant bearing for terminal flower

Answer 1

Axillary Flower (A) and Terminal Flower (a)

Thus,
Phenotypes of F1 generation is Axillary flower

Genotype ratio of F1 generation is Aa

Answer 2

Phenotype and genotype of F1 generation

Explanation:

• Auxiliary flower (A) and terminal flower (a)
• Phenotype: Axial flower × Terminal Flower
• Genotype: AA × aa
• Gametes: A, A × a, a
• 100% Axial flowers
• All progeny (100%) are Axial flowers if the plant characteristic trait is homozygous dominant.
• Phenotype: Axial flower × Terminal Flower
• Genotype: Aa × aa
• Gametes: A, a× a, a
• So, 50% progenies are Axial flowers and 50% progeny are terminal flowers if it the plant characteristic trait is heterozygous.
