Answer:
The correct answer would be c. 600
In Mendelian genetics, the genotypic ratio of F₂ generation is 1:2:1 and the phenotypic ratio of the same is 3 (dominant) : 1 (recessive).
Thus, tall and short plants in F₂ generation would also be in 3 (tall) : 1 (short).
Hence, there must be 600 tall plants (3 x 200) if there were 200 short plants.
The cross of the same is shown below in the attached figure.
