Solution

The correct option is D 4
Genotype of pure tall plant with green pod= TTGG
Genotype of pure dwarf plant with yellow pod= ttgg
P generation: TTGG X ttgg
F1 generation: TtGg(tall plant, green pod)
Selfing: TtGg X TtGg

TG(1/4) Tg(1/4) tG(1/4) tg(1/4)
TG(1/4) TTGG TTGg TtGG TtGg
Tg(1/4) TTGg TTgg TtGg Ttgg
tG(1/4) TtGG TtGg ttGG ttGg
tg(1/4) TtGg Ttgg ttGg ttgg

As can be seen from the table total 4 short plants with genotypes ttGG, ttGg, ttGg and ttgg are produced.
