...Khameeka N. Kitt Gene expression plays a pivotal role in the development, differentiation, and maintenance of organisms by allowing genes to encode for an observable trait (i.e., phenotype). To understand the function of a particular gene, several approaches can be taken, ranging from removing...

... interaction phenotype Textbooks describe epistasis as one of the classic variations on Mendel’s theme presenting genetic complexity beyond dominant and recessive. Epistasis causes a departure from Mendel’s standard segregation ratios ( Cordell, 2002 ). Epistasis is often defined as a gene-gene...

... and evolution often remains compartmentalized, and students struggle with thinking across levels. Thus, we present a classroom simulation of how selection affects both phenotypes and genotypes, which helps students distinguish between different levels of biological organization (i.e., phenotype and genotype...
