Step 1In genetics, inhibitory gene interaction and dominant suppressor gene interaction refer to two different types of relationships between genes that can affect the phenotypic expression of certain traits.
Here's a brief explanation of each concept: **Inhibitory Gene Interaction** Inhibitory gene interaction, also known as epistasis, occurs when the expression of one gene is masked or inhibited by the expression of another gene. This interaction can result in a phenotype that is different from what would be expected based on the genotype of either gene alone. For example, let's consider two genes, A and B, that control the expression of a particular trait. If A is an inhibitory gene for B, then the presence of the A gene will prevent the expression of the B gene, even if the B gene is present in the genotype. As a result, the phenotype will reflect the expression of the A gene only. **Dominant Suppressor Gene Interaction** A dominant suppressor gene interaction occurs when a dominant allele of one gene inhibits or suppresses the expression of a recessive allele of another gene. This interaction can result in a phenotype that is different from what would be expected based on the genotype of either gene alone. For example, let's consider two genes, C and D, that control the expression of a particular trait. If the dominant allele of gene C is a suppressor of the recessive allele of gene D, then the presence of the dominant allele of gene C will prevent the expression of the recessive allele of gene D. As a result, the phenotype will reflect the expression of the dominant allele of gene C and the dominant or recessive allele of gene D, depending on its presence. In summary, inhibitory gene interaction and dominant suppressor gene interaction are two types of gene interactions that can affect the phenotypic expression of certain traits. Inhibitory gene interaction occurs when the expression of one gene is masked or inhibited by the expression of another gene, while dominant suppressor gene interaction occurs when a dominant allele of one gene inhibits or suppresses the expression of a recessive allele of another gene.
