A couple is aware that a genetic condition frequently occurs in their families. They wish to have children without this condition, but do not want to know if they themselves have the gene for this late-developing illness. What are this couple's options for in vitro fertilization?
Select all that apply.
Note: Credit will be given only if all correct choices and no incorrect choices are selected.
◦ An embryo that does not have the genotype could be implanted.
◦ The couple could request that they not be told if any of the embryos not implanted had the genotype of concern.
◦ They could have multiple embryos placed during in vitro fertilization and hope that the one without the specific genotype is strongest and therefore implants.
◦ They could have in vitro fertilization with donor eggs and sperm without the genotype.
◦ No options exist for this situation with today's technology.
