Concept of Intergenic and Intragenic Gene Interaction

There are mainly two types of gene interactions namely intragenic and intergenic gene interaction. First, we will discuss the intergenic gene interaction. It is an interaction between two different genes located on either the same chromosome or different chromosome. To understand this concept, I have discussed it in detail on my video below: 

In the case of intragenic gene interaction, it is an interaction between two alleles of a gene present on the homologous chromosome. Please watch the video until the end to understand the concept in a very easy way.
