Definition
Epistasis is a genetic interaction where the effect of one gene is modified or suppressed by one or more other genes, influencing the expression of a particular phenotype. This interaction can result in the masking of the phenotypic effects of alleles at one locus by alleles at another locus.
Summary
Epistasis is a fascinating aspect of genetics that reveals how genes can interact in complex ways. It plays a crucial role in determining phenotypes, as one gene can mask or modify the expression of another. Understanding epistasis is essential for predicting inheritance patterns and studying traits in various organisms, from plants to animals. In practical applications, epistasis is significant in fields like agriculture and medicine. By recognizing how genes interact, scientists and breeders can make informed decisions to enhance desirable traits or understand genetic diseases. This knowledge is vital for advancing genetic research and improving breeding strategies.
