... a monohybrid cross. The offspring (F1’s) or zygotes of such a cross could also exhibit various genotypes and phenotypes depending on what the parents contribute. The monohybrid Punnett square is a graphical means to provide a visual understanding of all the possible outcomes between two parent contributions...

... interaction phenotype It is difficult to find two people with the exact same eye color and pattern since nutrition, environment, age, and expression of genes are variable. This suggests an “eco-evo-devo” element at work for generating novel phenotypes and diversity through the interaction of genes...

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...
