Sickle cell anemia, which is inherited as an autosomal codominant, also provides the opportunity to discuss classical Mendelian genetics. Further connections can be made to meiosis, gamete formation, and environmental influences that can affect phenotype. Lastly, sickle cell anemia provides an outstanding opportunity to build a connection between genetics and evolution. The two inherited alleles for a gene determine the phenotype for the trait. The DNA information provides instructions for building proteins.
Genetics research has applications in many different fields.
Genetics research raises many ethical, legal, and social issues.
