Alert - correct answer should be 4

Option 1 `Intervarietal` refers to the crossing between different varieties of the same species, and hence it qualifies as a type of hybridization. Option 2 `Interspecific` is a term used for crossing between different species but under the same genus, and it is also a type of hybridization. Option 3 `Intergenic` describes crossing between different genes i.e. crossing between different DNA segments of the genome of the same or different species, which is again a form of genetic hybridization.

Option 4 `Intragenic`, however, refers to the events happening within the same gene. It does not involve crossing of genetic material from different sources, therefore, does not qualify as a hybridization process. Hence, the correct answer should be option 4 - `Intragenic`.
