GENETIC EPISTASIS Meaning and
Definition
-
Genetic epistasis is a phenomenon in genetics where the effects of one gene are modified or masked by the presence of another gene or genes. It is a form of gene interaction that occurs when the expression of one gene is dependent on or influenced by the presence or absence of alleles at another gene loci. In other words, it is the interaction between different genes that affects the phenotype of an organism.
Epistasis can be classified into two main types: recessive and dominant. Recessive epistasis occurs when the presence of two recessive alleles at different gene loci leads to the suppression of a particular phenotype. On the other hand, dominant epistasis occurs when the presence of one dominant allele at a gene locus masks the expression of another gene.
Genetic epistasis plays a crucial role in determining the inheritance patterns of traits and the complexity of genetic pathways. It can result in a wide range of phenotypic variations, including the alteration or suppression of certain traits. Understanding epistasis is essential in fields like evolutionary biology, plant and animal breeding, and medical genetics, as it helps in deciphering the relationships between genes and their effects on an organism's phenotype.
In summary, genetic epistasis is a type of gene interaction in which the expression of one gene is modified or masked by the presence of another gene. It is an important factor in shaping the inheritance patterns and phenotypic variations observed in organisms.

Etymology of GENETIC EPISTASIS
The term "genetic epistasis" has its roots in both genetics and ancient Greek.
The word "genetic" refers to genetics, the scientific study of genes, heredity, and variation in living organisms. It comes from the Greek word "genetikos", meaning "origin", "generation", or "producing". It was first used in the context of biology in the early 20th century.
The word "epistasis" is derived from the Greek word "epi", meaning "upon" or "over", and "histemi", meaning "to stand". In genetics, epistasis refers to the phenomenon where the effect of one gene or allele is masked or modified by the presence of another gene or allele. It was first introduced by British biologist William Bateson in 1909.
