DNA and foetus. Conceptual computer artwork of a foetus surrounded by an autoradiogram (columns of small yellow bands) and a DNA (deoxyribonucleic acid) double helix (twisting yellow ribbons). The autoradiogram (also known as a 'DNA fingerprint') could represent the foetus's modified genes. This image could also represent genetic cloning as the autoradiogram could be another individual's genes, which the foetus has a replica of. Except for identical twins, no two individuals have the same genes. It could also imply testing the foetus's genes for genetic disorders (prenatal diagnosis) such as Down's syndrome.
