If the F1 generation produced by a cross between axial and terminal flower-bearing plants produces only axial flowers, the F2 progeny produced by the self-crossing of F1 will also produce only axial flowers.
If the F1 generation produced by a cross between axial and terminal flower-bearing plants produces only axial flowers, the F2 progeny produced by the self-crossing of F1 will also produce only axial flowers. Correct Answer False
The F1 progeny has only axial flowers, which imply that axial trait is dominant over the terminal trait. However, the F1 progeny are heterozygous. Upon self-crossing, 25% of the F2 progeny will be homozygous for the recessive trait, resulting in the formation of 3:1 ratio of axial flower-bearing to terminal flower-bearing plants.
