Types of Interactions between Non-allelic Genes

The inheritance and development of many traits depend on the types of interactions between non-allelic genes. Here are some types of interactions between non-allelic genes, listed in alphabetical order:

1. Complementation: Complementation occurs when two different recessive mutations in two non-allelic genes can produce a wild-type phenotype when combined in a heterozygous individual. This suggests that the two mutations affect different steps or components of a biological process.

2. Epistasis: Epistasis refers to the interaction between two or more genes where the effect of one gene masks or modifies the effect of another gene. In other words, the phenotype of one gene depends on the presence or absence of alleles at another gene locus.

3. Modifier genes: Modifier genes are non-allelic genes that can alter the phenotypic expression of another gene. These genes can enhance or suppress the effects of the target gene, leading to variations in the phenotype.

4. Polygenic inheritance: Polygenic inheritance occurs when multiple non-allelic genes contribute to the expression of a single trait. Each gene may have a small additive effect on the phenotype, and the combined effect of these genes determines the trait's expression.

Please note that this is not an exhaustive list of all types of interactions between non-allelic genes. There may be other types of interactions that are not mentioned here.
