1.	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.(a) True(b) FalseThis question was addressed to me in examination.This is a very interesting question from Inheritance of One Gene-2 in chapter Principles of Inheritance and Variation of Biology – Class 12
Answer» The correct option is (B) False The best I can explain: 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.
