Gregor Mendel, the father of classical genetics, made significant contributions to our understanding of this process. Dominant and recessive traits play a crucial role in determining an individual's characteristics. The difference between genotype and phenotype is also a key concept, illustrated here through the example of eye color.

Genes are sections of DNA that code for specific proteins or functional RNA. Alleles, on the other hand, are different versions of the same gene. They can lead to variations in traits like eye color. Understanding these differences is crucial to studying inheritance patterns.

The genetic condition phenylketonuria (PKU) is an example of how a genetic condition can be managed through environmental factors, like a specialized diet, to prevent negative outcomes.
