 Selection motivated by design, however, is performed with the aim of creating a child with characteristics which may or may not be possessed by the recipient parents but which are, nonetheless, deemed by them (and/or society) to be desirable (and often advantageous). Such selection may thus be performed with several aims in mind. These include but are not limited to desires to increase the life prospects of one’s children by preventing the birth of children with disadvantageous or without advantageous characteristics, to satisfy preferences for a particular ‘kind of child’, or with the eugenic aim of improving the gene pool through the selection of donors deemed to possess ‘superior’ heritable traits.
