high cost of procedure
What is a disadvatnage of embryo screening?
potential life might be destroyed by the parents, offspring is found to have possible genetic disorder in its genes
What is an ethical concern for embryo screening?
Sickle cell anemia
Which disease deforms the red blood cells, to prevent oxygen transportation, which makes them look like sickles?

gene therapy
Normal alleles are inserted into chromosomes of individuals with defective alleles.
They are destroyed.
