This is because the disease [Hint: make a Punnett square to figure this out.] A. occurs in individuals who received more than one allele from one or both parents B. is caused by having 2 copies of a recessive allele C. is caused by a dominant allele D. requires certain environmental expressed conditions to be

Hematology

Hematology is the branch of biology. Hematology is the medical field that deals with the treatment of blood disorders and cancers, such as hemophilia, leukemia, lymphoma, and sickle-cell anemia. Hematologists and hematopathologists are medical professionals who specialize in illnesses of the blood and its components.
