A pea plant from a pure-breeding strain that is tall, has green pods, and has purple flowers that are terminal is crossed to a plant from a pure-breeding strain that is dwarf, has yellow pods, and has white flowers that are axial. The F1 plants are all tall and have purple axial flowers as well as green pods. What proportion of the F2 progeny resulting from the self-cross of an F1 plant will resemble the dwarf parent from the parental generation?

Demarion Ho · Answer 1

the crossing of the F1 generation will result in the following;

tall green purple terminal : tall yellow purple terminal : dwarf green purple terminal : dwarf yellow purple terminal : tall green white terminal : tall yellow white terminal : dwarf green white terminal : dwarf yellow white terminal : tall green purple axial : tall yellow purple axial : dwarf green purple axial : dwarf yellow purple axial : tall green white axial : tall yellow white axial : dwarf green white axial : dwarf yellow white axial.

there is only one dwarf, yellow pod, white axial flower in the F2
