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 Genetics: Chromosomes, Genes, and Inheritance

Genetics encompasses the study of chromosomes, genes, and inheritance patterns. Chromosomes are bar-like structures carrying DNA, with homologous pairs determining traits. Autosomes and sex chromosomes play roles in genetic makeup. Genes are hereditary units determining individual traits, with allel

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
