Question
When two or more independent genes present on the same or different chromosomes interact to produce a new expression it is called:
Inter-genic gene interaction
Intra-genic gene interaction
Multiple allelism
None of the above
Inter-genic gene interaction
Intra-genic gene interaction
Multiple allelism
None of the above
Hint:
This type of gene interaction is also called as non-allelic gene interaction.
The correct answer is: Inter-genic gene interaction
- Intergenic interaction involves the interaction between two different alleles of different genes, which can be present on the same or different chromosome
- Epistasis, polygenic inheritance and complementary genes are examples of intergenic interaction.
