What is epistasis?      a gene at one locus alters the phenotypic expression of a gene at a second locus      having multiple phenotypic effects      when two alleles both affect the phenotype in separate distinguishable ways      a cross between an individual with an unknown genotype and a homozygous recessive individual

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.
