Complete a new Punnett Square below, for a woman who is a carrier for sickle cell, who is married to a man who has normal hemoglobin and is homozygous. A carrier for a recessive trait has a heterozygous genotype that "carries" the recessive allele without expressing it, since the dominant allele is expressed. Women or men can be carriers of traits on non-sex chromosomes, or autosomes. What are the possible genotypes that you can identify, do any of the possible genotypes result in sickle cell anemia, and what is the chance that any of the offspring are carriers for sickle cell anemia?

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.
