A single allele gives rise to the Hbs form of hemoglobin. Individuals who are homozygous for the allele (HbS/HbS) develop sickle-cell anemia (Section 9.6). Heterozygous individuals (HbA/HbS) have few symptoms. A couple who are both heterozygous for the HbS allele plan to have children. For each of the pregnancies, state the probability that they will have a child who is: a. homozygous for the HbS allele b. homozygous for the normal allele (HbA) c. heterozygous: HbA/HbS

Is it homozygous or heterozygous? 8. A pea plant exhibits a purple color, but you are unsure of its genotype. With what could you cross this plant to determine its genotype? Show all of your work for the cross. What is this type of cross called? Incomplete dominance: Genes code for the production of specific proteins, many of which are enzymes. Different alleles at a locus code for alternative forms of a protein that differ in structure and when the protein is an enzyme, often have different degrees of catalytic activity. Therefore, a heterozygote genotvpe produces an intermediate phenotype.
