Natural selection causes heritable phenotypic traits to become either more or less common in a population. Individuals with characteristics most suited to the environment are more likely to reproduce and survive. In this base, the human nature always attempts to be perfect during entire life as well. From beginning of life, human enhancement is going toward of being perfect, simple and pleasure life.
The gene engineering is one of human enhancement, which helps human to choose the interest genes for having the better life.
Gene selection can be helpful to screen genetic disorders and chromosomal abnormalities.
The purpose of gene selection should be either to prevent the birth of the babies showing genetic disorders or to terminate their lives ones they have already been born. So gene selection can play a role in eliminating genetic disorders from the population by genetic counseling of the parents who carry the defect genes.
Gene selection can lead to have children with potentialities that are higher than average. The process eliminates the genes that don’t meet the standard of the species.
In the reproductive gene selection, we can have two points of view, one of these is to have the best and ideal child and other is preventing of diseases and disables child.
‘ Couples (or single reproducers) should select the child, of the possible children they could have, who is expected to have the best life, or at least as good a life as the others, based on the relevant, available information ‘ -Savulescu 2001.
According to these views, if we consider two different couples that wants gene selection for their future child, a couple that has the defect or mutant disabled genes in their family history and wants to have a healthy child ‘as good as others’ in the versus of couples who wants to improve the physical appearances like eye colors and intelligence child.
Of course first couples wishes are more acceptable because of if their child born with physical disorders, the life could be difficult for that child and in the other hand the care and health insurance costs will be higher for the parents as well as for the society, because this kind of individuals need special care.
Second couple also wants reproductive gene selection for their child if this one is also in the category of perfectionist view?
For answer of this question we need following examples:
‘The Wine Capacity Case: Suppose that a couple is having in vitro fertilization (IVF) in an attempt to have a child. The process produces two embryos. A battery of tests for common diseases is performed, and it is found that Embryo A has no abnormalities on the tests performed, except that its genetic profile reveals that it has a predisposition to be able to enjoy super fine wine; and Embryo B has no abnormalities on the tests performed except its genetic profile reveals it has a predisposition to be able to enjoy very fine wine, but not super fine wine. Let …
