Question

In pea plants, when a true-breeding line with axial flowers is crossed with a true-breeding line with terminal flowers, all of the F1 offspring have axial flowers. What phenotypic ratio is expected in the F2 generation?

Answer 1

Answer:

3/4 axial flowers and 1/4 terminal flower

Explanation:

A cross between two true breeding with the axial flowers been dominant to the terminal flowers will produce first generation offspring with axial flowers that are not true breeding (heterozygous in genotype but still axial flowers in phenotype). In the F2 generation, which might be a cross between the the F2 generations will produce

3/4 axial flowers and 1/4 terminal flower
