Overview
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...
Key Terms
Example: In Labrador retrievers, the gene for coat color is epistatic to the gene for pigment deposition.
Example: In squash, a dominant allele can prevent the expression of color genes.
Example: In mice, the presence of two recessive alleles can prevent pigment production.
Example: A modifier gene can enhance or suppress the effect of a primary gene.
Example: Flower color in plants is a phenotype influenced by multiple genes.
Example: The genotype of a pea plant can determine its flower color.
