Genetic Selection and Medical Motives

Ova and sperm can be genotyped so that particular genes or combinations of genes can be selected. While this is usually very expensive and not yet foolproof, success has been reported in influencing the sex of a child.

Cells from early embryos can be removed for even more precise geno-typic determination and selection. Such selection has the potential of being more and more precise. Technology may even become capable of altering traits, as the genome becomes better understood. What kind of genetic selection should be allowable in embryos? Should one avoid mental retardation in potential children? Should one select for possibilities of greater intelligence? Is it ethical to choose to have a child only of a particular sex?

Genetic analysis also allows parents to have children whose genes can help others. But should a child be brought into the world simply for the genome the total genetic material in a cell or organism
