WebJan 12, 2024 · Broadly, this faith in the large-scale quantification of phenotypic data for solving genotype–phenotype riddles is aligned with Houle et al.'s (2010) influential article advocating a phenomics approach in biology, comparable to the genomics approach, to better understand the pathways connecting genotypes to phenotypes: “The question ‘why ... WebEpistasis is a polygenic interaction at different loci, where one gene controls the expression of the other gene for a given phenotype. Both genes are required for the trait to be expressed. However, one trait is epistatic to the other, meaning, it will control if it will get expressed or not.
