Epistasis - PowerPoint PPT Presentation


Understanding Epistasis: Types and Inferences

Epistasis is the interaction between genes where one gene's allele masks the expression of another gene. Various types of epistasis, such as dominant and recessive epistasis, can be observed, impacting the phenotypic ratios. Statistical inferences can help analyze epistatic interactions in genetic s

Understanding Epistasis: Genetic Interactions and Their Implications

Epistasis is a phenomenon where the phenotypic expression of one gene is influenced by interactions with another gene. This concept, first introduced in 1909, plays a crucial role in genetics, affecting various traits and evolutionary processes. The difference between dominance and epistasis lies in

Genetic Interactions in Chicken Combs: Epistatic and Non-Epistatic Examples

In chicken genetics, epistatic and non-epistatic interactions play a crucial role in determining comb size and shape. Bateson and Punnett's studies on fowls revealed how different gene pairs interact to produce distinctive phenotypes. Epistatic interactions, such as dominant epistasis, influence the
