Fundamentals of Genetics: Genotype and Phenotype

The video tutorial explains observable traits, known as phenotypes, and their genetic basis, called genotypes. It uses examples like peapod color and earlobe attachment to illustrate how genotypes determine phenotypes. Dominant and recessive traits are discussed, with a focus on earlobe attachment, where unattached earlobes are dominant and attached earlobes are recessive.
