Because the main reason to use cloning in the above case is to have children who are genetically related to at least one member of the couple, Strong questions whether reasons can be given to the value of genetically related children (150). One such reason offered by the writer is the value of the participation in the creation of a person. The member of the couple whose chromosomes are used would participate by providing the genetic material for the new person, and the other may participate by gestating and giving birth to the child. One might object that the infertile couple could still participate in the creation of a person by using donor gametes or pre-embryos. In reply, although the above methods also constitute types of participation, a more direct involvement would occur if one member of the couple contributed genetically to the creation of the child. In this sense, cloning can be understood as a superior reproductive procedure than its alternatives.
Another advantage is the modification of genetic traits in human beings. Human genetic engineering science modifies human beings genotypes before birth. This process can be utilized to manipulate some traits in people. Genetic engineering can be employed to suppress negative traits while boosting positive ones. Positive genetic engineering is concerned with the enhancement of positive individual traits. This includes increasing human capacity or longevity. Conversely, negative genetic engineering is concerned with the quelling of negative human traits such as some genetic diseases.
