All clones are asexually reproduced offspring. All in vitro fertilization offspring are test-tube babies. Some in vitro fertilization offspring are not test-tube babies. No forms of artificial insemination are ethical forms. All formations of children who are well cared for are ethical formations.
All clones are artificial births.
All places where there are artificial births are places where there are ethical questions. All times that new medical technologies arise are times that ethical questions arise.
