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 F1F1 plants are all tall and have purple axial flowers as well as green pods. a. What phenotypes do you expect to see in the F2?F2? b. What phenotypes and ratios would you predict in the progeny from crossing an F1F1 plant to the dwarf parent?

GGPP x ggpp= GgPp, GgPp, GgPp, GgPp 4:0 All tall

GgPp X GgPp= GGPP, GgPp, GgPp, ggpp 3:1 Three tall one dwarf

GgPp x ggpp= GgPp, GgPp, ggpp, ggpp 2:2 two tall n two dwarf

Step-by-step explanation:

It will result into two dwarf homozygous offspring and two heterozygous tall offspring.
