The formula to calculate the Phenotype Ratio (R) is:
\[ R = D : R \]
Where:
A phenotype ratio is a way of expressing the relative number of different phenotypes observed in a group of organisms. In genetics, phenotypes refer to the observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences. The phenotype ratio is often used to predict the outcome of genetic crosses and to understand the inheritance patterns of specific traits. For example, in a simple Mendelian inheritance scenario, the phenotype ratio can help determine the likelihood of offspring exhibiting dominant or recessive traits.
