The comb shape of chickens is an example of an interesting inheritance pattern.  Two genes, each with a dominant and recessive allele, determine comb phenotypes as follows: Comb Shape Description Genotype Single Comb homozygous recessive for both r and p rrpp Walnut comb both dominant alleles are present; R and P alleles are present R_P_ Pea comb the dominant allele P is present and the dominant allele R is absent rrP_ Rose comb the dominant allele R is present and the dominant allele P is absent R_pp Which of the following represents the correct phenotypes of the F2 offspring? Select one: a. Phenotype Single Walnut Pea Rose 9/16 3/16 3/16 1/16 b. Phenotype Single Walnut Pea Rose 3/16 1/16 9/16 3/16 c. Phenotype Single Walnut Pea Rose 1/16 9/16 3/16 3/16 d. Phenotype Single Walnut Pea Rose 3/16 9/16 1/16 3/16

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.
