A blastomere was removed from an 8-cell human embryo, and its beta-globin gene was amplified by PCR. The beta-globin DNA was treated with an enzyme that cuts on either side of and within the normal allele (producing a small fragment), but not within the sickle cell allele (producing a large fragment). Electrophoresis of the treated DNA from the blastomere demonstrated the presence of both a large and small fragment derived from the beta-globin genes. How should you interpret this test?

the embryo will have totally normal hemoglobin

the embryo will develop sickle cell trait

the embryo will become twins: one with sickle cell anemia and the other normal

the embryo will develop both sickle cell anemia and beta-thalassemia

the embryo will develop sickle cell anemia

the embryo will develop sickle cell trait

As the enzyme cut the normal allele and did not cut the abnormal allele . Its mean that cell has one normal allele and one abnormal allele.. if both were abnormal then enzyme would cut both into small fragments...

yeah.... the embryo will develop sickle cell trait.
