Which of the following is an example of intergeneric hybridization?
Triticale
Raphanobrassica
Gossypium hirsutum
More than one option is correct
Option (4) "More than one option is correct" is the correct answer. Both (1) Triticale and (2) Raphanobrassica are examples of intergeneric hybridization.
Option (3) Gossypium hirsutum refers to upland cotton, which is not an example of intergeneric hybridization. Gossypium hirsutum is a species within the same genus (Gossypium), so it involves intraspecific hybridization rather than intergeneric hybridization.
Hence, the correct answer is option 4.
