EPISTATIC GENES Meaning and
Definition
-
Epistatic genes refer to a specific class of genes that exert control or influence over the expression of other genes. These genes can either enhance or suppress the expression of other genes, thereby affecting the phenotype or observable characteristics of an organism.
Epistasis is a phenomenon in genetics where the effect of one gene masks or modifies the effect of another gene, which may be located at a different genetic locus. The gene that exerts the controlling effect is known as the epistatic gene, while the gene whose expression is affected is called the hypostatic gene.
Epistatic genes play a crucial role in various biological processes and can have significant impacts on the phenotype of an organism. They contribute to genetic interactions and can influence traits such as coat color, eye color, and disease susceptibility.
There are different types of epistasis, including dominant and recessive epistasis, as well as duplicate gene interactions. Dominant epistasis occurs when the presence of at least one dominant allele in an epistatic gene masks the expression of another gene. Recessive epistasis occurs when the presence of two recessive alleles in an epistatic gene prevents the expression of another gene. In duplicate gene interactions, multiple genes are involved, and the presence or absence of specific alleles in any of these genes can produce different phenotypic effects.
Overall, epistatic genes are key components of genetic networks, influencing the expression and interactions of other genes, and contributing to the complexity and diversity of traits observed in living organisms.

Etymology of EPISTATIC GENES
The word "epistatic" comes from the Greek word "epi" meaning "upon" or "above", and the word "stasis" meaning "standing" or "stability". In genetics, an epistatic gene is a gene that can mask the effect of another gene at a different locus. This term was coined to describe the phenomenon of gene interactions in which the expression of one gene overrides or modifies the expression of another gene.
The word "genes" on the other hand, comes from the Latin word "genus", which means "kind" or "race". It is used to refer to the segments of DNA that encode specific traits or characteristics in organisms.
Therefore, the term "epistatic genes" refers to the genes that interact in a way that one gene's expression affects or modifies another gene's expression, leading to a combined effect on trait expression.
