What is the Difference Between Allelic and Non allelic Gene?
🆚 Go to Comparative Table 🆚The difference between allelic and non-allelic genes lies in their position on the chromosomes and their interaction with each other. Here are the key differences:
- Position on chromosomes: Allelic genes are alternative forms of a gene that are present at the same location on homologous chromosomes. In contrast, non-allelic genes are present at different locations on the same homologous chromosome.
- Interaction: Allelic genes interact with each other, which is referred to as allelic or non-epistatic gene interaction. This interaction occurs between the alleles of a single gene and can result in different phenotypes, such as in incomplete dominance. Non-allelic genes, on the other hand, interact with each other in a way that involves interactions between genes on identical or distinct chromosomes. This interaction is referred to as non-allelic or epistatic gene interaction.
In summary, allelic genes are alternative forms of a gene located at the same position on homologous chromosomes and interact with each other, while non-allelic genes are located at different positions on the same homologous chromosome and interact with each other in a way that involves interactions between genes on identical or distinct chromosomes.

Comparative Table: Allelic vs Non allelic Gene
Here is a table comparing allelic and non-allelic genes:
Allelic Genes | Non-allelic Genes |
---|---|
Alleles are present at the same location on homologous chromosomes. | Alleles are present at different locations on the same homologous chromosomes. |
Responsible for different characteristics in an organism. | Also responsible for different characteristics in an organism. |
Genetic interactions between alleles of a single gene are referred to as allelic or intra-allelic interactions. | Genetic interactions between alleles of different genes are referred to as non-allelic or inter-allelic interactions. |
Mendelian ratios do not explain all types of inheritance patterns. | Mendelian ratios also do not explain all types of inheritance patterns. |
Deviations from Mendelian traits are referred to as interactions of genes or factor hypothesis. | Deviations from Mendelian traits are also referred to as interactions of genes or factor hypothesis. |
Both allelic and non-allelic genes affect gene expression in different ways due to their interactions.
