Sickle cell anemia causes hemoglobin, the oxygen - carrying molecule of red blood cells, to be misshapen resulting in disease. "H" is the normal hemoglobin allele and "h" is the allele for sickle - cell shaped hemoglobin. In order to get the disease, a person must have a recessive genotype (hh). Two people with normal red blood cells are carriers of the gene - they have m genotypes Hh. Questions: a. What are the possible genotypes of the eggs the woman can produce? b. What are the possible genotypes of the sperm the man can produce? c. What is the genotypic ration for the offspring? d. What is the phenotype ratio for the offspring? e. What is the couple's chance of having a child a sickle
