PilotLPTM [1.2K]

Answer:

The correct answer will be option-C.

Explanation:

Gregor Mendel is known for his experiments performed on the pea plants on the basis of which he was able to predict the principles of inheritance. He used seven different characters to understand the inheritance pattern of the traits in generations.

He performed monohybrid (single) and dihybrid (two) crosses by growing the plants from the seeds and performing cross-fertilization and self-fertilization. He performed self- fertilization by emasculation and cross-fertilization by shedding the pollen of another plant over ovules of another plant.

Thus, Option-C is the correct answer.
