Laboratory baby. Conceptual computer artwork of a human baby inside a glass laboratory flask,representing human cloning,or a test tube or designer baby. Human cloning can,in theory,generate a person whose genetic material,or DNA (deoxyribonucleic acid),is identical to that of another person,by replacing the DNA present in a human egg with DNA of the person to be cloned. A test tube baby is created by the fertilization of a mother's egg with the father's sperm in the laboratory,a process known as in vitro fertilization (IVF). A designer baby is one whose genetic composition has been chosen,to any extent,by its parents |
