Solution:
Intergenic interaction is shown by polygenes. This type of interaction occurs when two or more alleles of different genes present on same or different chromosomes interact to produce a cumulative effect. Multiple alleles, co-dominance and incomplete dominance are the examples of intragenic interactions.
