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.

Question

If the A and the S alleles are co-dominant. What is the phenotype of a heterozygote (AS)?

Definition Definition Observable physical traits or characteristics of an organism, which are determined by its genetic makeup (genotype) as well as environmental factors. These traits can include anything from eye color or height to behavior or disease susceptibility. Understanding an organism's phenotype is important in fields such as genetics, medicine, and ecology.

Expert Solution

Step 1: Codominance

Codominance is a genetic concept where two different alleles of a gene are equally expressed in a heterozygous individual, and neither allele is dominant over the other. This results in both alleles being visibly expressed in the phenotype, often producing a unique or blended trait.
