n mice, the Ay allele of the agouti gene is recessive lethal, but it is dominant to wild type for yellow coat color. For an unlinked gene called C, cc makes no pigment and are albino while C_ mice will make pigment in in their coat. cc is epistatic to A or AY with regard to coat color, but not for viability. What phenotypic ratio would you expect from the progeny produced by two mice of the genotype: AAy Cc? (Note that “agouti” is the wild-type coat color.)     9 agouti : 3 black : 3 white : 1 yellow     3 agouti : 6 yellow : 3 white     12 yellow : 3 black: 1 brown     9 agouti : 3 yellow : 4 white       8 yellow : 3 black: 1 brown

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.
